I've studied nursing for two years, put it on hold and started medicine. For my first two years in nursing, your videos helped so much!! Even biochemistry and other subjects, but especially physiology. Got 10/10 for that subject and still proud. I'm still viewing them for medicine and they help a lot. Thank you so much for the time spent explaining these subjects in detail.
I've studed medicin in Denmark for 3 years now, and i've used your lectures for every module, and I couldn't have done it without you. So thank you! And thank you for being so inspiring in your lectures - your passion really shines through i every single video!
Notes part 1/3 kidney kidney bean shaped two present in abdominal cavity There is connective tissue surrounding the kidney- there are three layers 1. renal capsule- made up of loose connective tissue prevents certain types of infectious micro organism from spreading into the kidney there is other connective tissue surrounding it like outside of this one, more superficial to this one which is called the 2. perirenal fat capsule and that's a adipose tissue that's surrounds it It is helpful for being able to cushion the kidneys 3. renal fascia- dense fiberous irregular connective tissue that anchors it to the actual surrounding structures to keep it retroperitoneal, which means behind There's like a slit-like space where the renal arteries going in, the renal vein is coming out, and the ureter is coming out. -That’s called the renal hilus It is very different from the renal sinus The renal sinus is like a plumbing of the kidney. It's like this area or this space, which consist of the renal pelvis the renal artery, the renal veins, and other different structures in this area. outer granulated tissue All the way around is called the cortex, it's called the renal cortex Deep in the kidney is little dark striated types of tissue. That is called the renal medulla - looks like a pyramid, renal pyramid number 23 -inward extension of the cortical tissue and it dips down into the medulla These are called the renal columns, the renal columns are inwards extensions of the cortex the end of renal pyramid , this is the renal pyramid part of the renal medulla at the end of the renal medulla all the way at the bottom the end part right there number 6, is called the renal papilla renal papilla-empties the urine, into this little like tube called the minor calyx multiple minor calyces come together, to form a major calyx The major calyces will join to form big structure which is called the renal pelvis, number 4. the renal pelvis exits the kidney and goes out of the hilus renal pelvis exits the kidney as the ureter the blood flow to the kidney abdominal aorta into the kidney. Off the abdominal aorta there is an artery - number 2. That number 2 is called the renal artery (lat: a. renalis). The renal artery, once it enters into the kidney through the hilus it splits into 2a. 2A is called the segmentary artery the segmental artery goes into what's called the interlobar arteryNumber 13 a lobe- the renal pyramid and the surrounding cortical tissue. The artery here is called the interlobar artery The interlobar artery runs inbetween the two lobes the interlobar artery as it gets to the top part of the cortex, it starts branching off this branch is called the arcuate artery - number 16 Then the arcuate artery as it's moving up it gives off these branches, these ones that are getting radiated up into the cortex is called the cortical radiated artery cortical radiated artery has an afferent arteriole. cortical radiated artery feeds into an afferent arteriole, then into the glomerulus and then through the efferent arteriole and then it comes out of the efferent arteriole and then it goes to peritubular capillaries. From the peritubular capillaries, it comes down through the cortical radiated veins The cortical radiated vein then moves back down it joins with the arcuate vein cortical radiated vein joins with the arcuate vein, and empties into the interlobar vein the interlobar vein joins with other interlobar veins and form the renal vein - number 1 there's no segmental veins an enlarged view of a kidney lobe lobe defined as the renal pyramid and it's surrounding cortical tissue Now, let's keep going and show you what I couldn't show you before interlobar artery number 12 is moving up and then asit moves up, it gives off that branch, around the actual cortex, it gives off this branch right here so number 7 so following up is interlobar then it gives off a branch which is called the arcuate artery Now,the arcuate artery is gonna start feed up here number 8, as we follow this all the way up
My teacher is good, but since the class went online, I feel lost. No lab, no class. Just short video lectures no where as detailed as the in class learning. I love this video! It is making sense of the lecture and the book. This corona virus is making it hard to learn anatomy, especially if you never know when you will be called to help out in the covid dedicated unit, or on your home unit. Thank you so much for the video
You save me once again …. with the help of your biochemistry videos I passed my BC exam as 3rd best … Thank god I found out u also posted videos about renal physiology (Physiology is my next exam) … the kidney has always been a mystery to me ever since but after watching your videos it suddenly all makes sense!!! Thank u so so so much - You are amazing!!! - German med student
i cant stop praising ur explanations skills. Uncountable thanking u for helping students like us get to survive through online classes. Sending lotssssss of love from Pakistan.
May allah see me good no but platinum wing foryou iam saliented all beinng for withme but junping hihgh playing sikiping not me but all daliey hares play selfed physiolodecal make now lot of money forget go ok not hlping seegod se why ate juping no monney ok 1yyer home good helping gues dont warried bai for get
Thank you for connecting the dots! Between my asynchronous lectures and the 2d book, I am left wondering about so much. You are so thorough and efficient and then you even reiterate which is the most helpful
I love your channel! Also really appreciate that you repeat terms and explanations over and over, it really helps solidify things in my mind. You are helping so many people, thank you for doing what you do!
Let me just say, since the Pandemic you have been like a savior! I had been trying to get acceptance to my dream career for years and finally, my dream came true last spring when I found out I was accepted. Unfortunately, COVID-19 came and my program started this past May during the height of the Pandemic. Needless to say, school was transitioned online and me having graduated undergrad 10 years ago, I was not up to speed and had to re-learn how to become an adult learner again. Trying to learn these complex concepts through zoom is not ideal. I go to an Ivy league but during times like this, all it is is just a name. No access to lab, campus, or tutoring your videos has definitely saved me. You have a special gift and your style of teaching breaks through to me! I love my professor but often times I feel more confused than before I started. You are very precise and explain things in a way to easily understand. Thank you so much!
No one in med school ever explained it to me this subject this detailed. Thank you very much. Please, continue doing the perfect job you are born for :*
You are seriously loved over here, like students appreciate you so much☺️. I'm all the way at a Caribbean med school, and your videos help so many of us when the concepts are hard to grasp in class. From my first year, first semester, I've been hearing nothing but "don't understand? Watch Ninja nerd!" For physiology and anatomy, especially. I don't know if you know just how many students all over the world you're helping, and (saving) our grades, because alot of us can't really afford extra lessons or premium classes delivered by other RUclips channels. You do all that they do, and for free. I hope you know how much we appreciate you. Thank you for all that you do😊❤
You guy explain it easily every thing about kidney anatomy you explain very clearly.it is very difficult to read out or learn the lengthy stuff material of anatomy books but your this lecture made me that I could write suffecient materials in my exam.
the most informative video for this topic thank u so much -- for the ones who are first time watching this listen to me go finish all the ninja nerds physiological videos and then watch this video again u will appreciate this video so much
You are freaking AMAZING!! love love your teaching skills. I was able to retain all of my terms for my lab exam thanks to you! :) Thank you so much. May God bless you.
I just want to say thank you, there’s no other word! Thanks for being such a good professor, I understand every word my professor said when she was explaining something about the nephron… I came here 2 months ago, I didn’t understand any about respiratory physiology because my professor explained everything without images and just text! And I am a very visual person🤦🏻♀️thanks to you I understand respiratory and renal physiology, I even got 81 at my Renal Exam! It wouldn’t happened if it wasn’t for you, thanks a lot again 😄
hey just wanna tell u that u have kept all of this treasure absolutely free which is a blessing itself.. ure teachings, personality and how ure able to connect thru screen is a god gifted talent and ure making it all useful for us. i am utterlyy grateful to u. i just found out i failed my university exams and im repeating all my concepts. i cant see light anywhere, everything is ten times harder but u comfort me thru these videos. thankyou
Thank you so much for this video! This is high quality video and FREE with a detailed explanation from you and relevant sample for better understanding of the student. The content is precise and on point.
Notes 2/3 it's like a branch going straight into the cortex here is called the cortical radiated artery, cortical radiated artery give off branches, called a renal corpuscle That little branch right there is an afferent arteriole 9 is the afferent arteriole. the afferent arteriole feeds into a renal corpusculum renal corpusculum made up of a tuft of capillaries which is called the glomerulus and the surrounding Bowmann capsule afferent arteriole feeds into a renal corpusculum. and then it gets drained by another arteriole, called the efferent arteriole So it's going in to here, getting filtered through the glomerulus and coming out of the efferent arteriole, number 10 interlobar, arcuate,cortical radiated, afferent, glomerulus, efferent. efferent arteriole as they're coming out they start branching into smaller little capillary networks called the peritubular capillaries. The peritubular capillaries are important for secretion absorption, as we drain the peritubular capillaries, they all drain into this main vein, called the cortical radiated vein so it’s bringing the actual blood, deoxygenated blood,all the way down from the cortex going towards the medulla this cortical radiated vein is coming down, Its gonna join with arcuate vein big big peritubular capillary network is called vasa recta efferent arteriole, gives off a branch that feeds deep down into the medulla and forms this capillary network, and this capillary network is called the vasa recta. It's very important for being able to concentrate urine vasa recta has blood that can also drain into arcuate vein So arcuate vein, blood from the vasa recta and the cortical radiated vein all dump their blood into this main moving down inbetween the lobes, so this main vein coming all the way down here is going to be number 12 the interlobar vein. the interlobar vein will feed into the renal vein and then go back to the inferior vena cava. inside the Bowmans capsule 20, it's a little capillary network called the glomerulus. glomerulus filters certain types of plasma components out of the blood and into the little like tubes here. The membrane here that's surrounding it all the way around is called the Bowmans capsule once the fluid that plasmas filtered to, it drains into this Bowmans capsule and then it goes into this like coiled tube. called proximal convoluted tubule. proximal convoluted tubule goes down to the descending limp of the loop of Henle, and it comes back up to the ascending limb of the loop of Henle. Then as it comes up back into the cortex, look, it starts getting coiled and is called the distale convoluted tubule. Bowman's capsule,proximal convoluted tubule, descending limb,thin section, ascending limb, distale convoluted tubule. The distale convoluted tubule dumps its filtrate the collecting duct number 6 Bowmans capsule, proximale convoluted tubule, loop of Henle and distal convoluted tubule makes up the nephron renal corpusculum is the glomerulus and the Bowmans capsule Now as the filtrate actually moving down the collecting duct, it'll get to the end of renal called the renal papilla, there's a little duct portion here at the renal papilla called the papillary duct And once its at the papillary duct, it's now urine it drops off of the papillary duct of the renal papilla, and into that minor calyx. renal corpusculum It is the glomerus capillaries and the surrounding, it's called,Bowmans Capsule Afferent feeds the glomerulus capillaries and efferent (7) drains the glomerulus capillaries afferent arteriole have cells called JG-cells, or juxtaglomerularcells. These juxtaglomerularcells are pressure-receptors. They are baro-receptors and mechano-receptors and they can have the ability to sense changes in blood pressure and stretch. When that happens, they have vesicules that they can secrete specific types of chemicals, like renin and renin helps to regulate our blood pressure things in the back is a portion of the distal convoluted tubule. distale convoluted tubule, have these specific cells, that are like chemo-receptors
Notes 3/3 they pick up different chemical concentrations These cells here are called the macula densa cells juxtaglomerular-apparatus and it consists of the JG-cells in the afferent arteriole, and the macula densa cells in the distal convolute tubule, glomerulus is this tuft of capillaries and it's fenestrated capillaries his is actually the raw capillaries here theres this like beige tan covering on it They're having cells clinging to the capillaries and forms the visceral layer of Bowmans capsule, and this visceral layer of Bowmans capsule is these simple squamous cells, modified simple squamous cells they're called podocyts, which means foot cells podocyts are clinging on to these glomerulus capillaries, and these are forming the visceral layer of the Bowmans capsule outer layer out here, and whole out thing here is made up of simple squamous epithelial cells too, but this whole outer layer here that's even continous with this actual podocyts visceral layer. This layer here is called the parietal layer of Bowmans capsule, The podocytes make up the visceral layer of the Bowman capsule and this outer part is the parietal layer of the Bowman capsule Bowmans capsule is getting drained by this next structure, like little like simple cuboidal epithelial cells called the proximale convoluted tubule. It processes a lot of different types of nutrients and solutes and small proteins afferent arteriole is consisting of the JG-cells,releasing renin that controls blood pressure, so they're baroreceptors, efferent arteriole, the macula densa cells, which are a part of the distal convoluted tubule they're like chemo-receptors and then this whole area of the macula densa cells and the JG-cells is the juxtaglomerular apparatus These cells are clining to the actual glomerulus capillaries, and is called podocyts they form the visceral layer of Bowmans capsule The glomerulus capillaries are fenestrated capillaries very porous and outer layer here is called the parietal layer of the Bowman Capsule,it's also very continous with the visceral layer and then we have the proximal convoluted tubule down here, which is very important for absorbing specific types of nutrients, and for secretion of like, certains types of chemicals.
The video provides an in-depth look at kidney anatomy, detailing the layers of connective tissue that protect and cushion the kidneys, as well as the structure of the renal hilus and renal sinus. It also explains the blood flow through the kidneys, starting from the renal artery and branching into smaller vessels, ultimately leading to the nephron. The video covers key structures such as the glomerulus and Bowman's capsule, which are essential for filtration and urine production, highlighting their role in maintaining kidney function.

Notes part 1/3
kidney
kidney bean shaped
two present in abdominal cavity
There is connective tissue surrounding the kidney- there are three layers
1. renal capsule- made up of loose connective tissue
prevents certain types of infectious micro organism from spreading into the kidney
there is other connective tissue surrounding it like outside of this one, more superficial to this one which is called the 2. perirenal fat capsule and that's a adipose tissue that's surrounds it
It is helpful for being able to cushion the kidneys
3. renal fascia- dense fiberous irregular connective tissue that anchors it to the actual surrounding structures to keep it retroperitoneal, which means behind
There's like a slit-like space where the renal arteries going in, the renal vein is coming out, and the ureter is coming out. -That’s called the renal hilus
It is very different from the renal sinus
The renal sinus is like a plumbing of the kidney. It's like this area or this space, which consist of the renal pelvis the renal artery, the renal veins, and other different structures in this area.
outer granulated tissue All the way around is called the cortex, it's called the renal cortex
Deep in the kidney is little dark striated types of tissue. That is called the renal medulla - looks like a pyramid, renal pyramid
number 23 -inward extension of the cortical tissue and it dips down into the medulla
These are called the renal columns,
the renal columns are inwards extensions of the cortex
the end of renal pyramid , this is the renal pyramid part of the renal medulla
at the end of the renal medulla all the way at the bottom the end part right there number 6, is called the renal papilla
renal papilla-empties the urine, into this little like tube called the minor calyx
multiple minor calyces come together, to form a major calyx
The major calyces will join to form big structure which is called the renal pelvis, number 4.
the renal pelvis exits the kidney and goes out of the hilus
renal pelvis exits the kidney as the ureter
the blood flow to the kidney
abdominal aorta into the kidney.
Off the abdominal aorta there is an artery - number 2. That number 2 is called the renal artery (lat: a. renalis).
The renal artery, once it enters into the kidney through the hilus it splits into 2a.
2A is called the segmentary artery
the segmental artery goes into what's called the interlobar arteryNumber 13
a lobe- the renal pyramid and the surrounding cortical tissue.
The artery here is called the interlobar artery
The interlobar artery runs inbetween the two lobes
the interlobar artery as it gets to the top part of the cortex, it starts branching off
this branch is called the arcuate artery - number 16
Then the arcuate artery as it's moving up it gives off these branches,
these ones that are getting radiated up into the cortex is called the cortical radiated artery
cortical radiated artery has an afferent arteriole.
cortical radiated artery feeds into an afferent arteriole, then into the glomerulus and then through the efferent arteriole and then it comes out of the efferent arteriole and then it goes to peritubular capillaries.
From the peritubular capillaries, it comes down through the cortical radiated veins
The cortical radiated vein then moves back down
it joins with the arcuate vein
cortical radiated vein joins with the arcuate vein, and empties into the interlobar vein
the interlobar vein joins with other interlobar veins and form the renal vein - number 1
there's no segmental veins
an enlarged view of a kidney lobe
lobe defined as the renal pyramid and it's surrounding cortical tissue
Now, let's keep going and show you what I couldn't show you before
interlobar artery number 12 is moving up and then asit moves up, it gives off that branch, around the actual cortex, it gives off this branch right here so number 7 so following up is interlobar
then it gives off a branch which is called the arcuate artery
Now,the arcuate artery is gonna start feed up here number 8, as we follow this all the way up
you are my savior! thank you!!!

Watched on my dinner break and learned a ton. Taking TEAS and did a practice test & a nephron question popped up.
Thank you!
I can't thank u enough ninja nerd it's one of my dreams meeting u in person,best there is and they'll ever be👊
Woww. Never ever have I seen anyone explaining like this. Amazing. Thank you very much. This makes learning very interesting :)
Best video of kidney anatomy ever!
yes it's very helpful and clear many things. short & sweet way of teaching thanks a lot. May Allah give you reward what you deserve.
How wonderfully explained. Everything makes sense now. Thank you so so much.
You and the team deserve awards!!!
I watch this video every time i study something related to renal system and it’s kinda cool!
I have been confusing for months until found this one. Thank you so much for showing this.
Your videos are amazing. Keep up the good work sir! Was able to learn a lot with a whole lot of the concepts with a better understanding.
This was literally the best explanation ever, holy Jesus.
Thankyou so much sir because of your vedios I become able to pass my part 1 residency exam May Allah bless you ❤️
You make the world a better place. Thank you for your amazing videos.
Your explanation is very detailed Can you PLEASE keep up the good work and keep your lessons very detailed AMASING Vedio you have
Very save in your class,am confident in my anaesthesia training may the Lord protect you
You explained everything so good, thank you I have my practical in a few days.
Loved those models and your explanation!! Made everything so clear! So much better than diagrams drawn on a board! Thank you so much!❤️❤️
stopping by to say thanks again... never enough thanks.
Notes 2/3
it's like a branch going straight into the cortex here is called the cortical radiated artery,
cortical radiated artery give off branches, called a renal corpuscle
That little branch right there is an afferent arteriole
9 is the afferent arteriole.
the afferent arteriole feeds into a renal corpusculum
renal corpusculum made up of a tuft of capillaries which is called the glomerulus and the surrounding Bowmann capsule
afferent arteriole feeds into a renal corpusculum.
and then it gets drained by another arteriole, called the efferent arteriole
So it's going in to here, getting filtered through the glomerulus and coming out of the efferent arteriole, number 10
interlobar, arcuate,cortical radiated, afferent, glomerulus, efferent.
efferent arteriole as they're coming out they start branching into smaller little capillary networks called the peritubular capillaries.
The peritubular capillaries are important for secretion absorption,
as we drain the peritubular capillaries, they all drain into this main vein, called the cortical radiated vein
so it’s bringing the actual blood, deoxygenated blood,all the way down from the cortex going towards the medulla
this cortical radiated vein is coming down,
Its gonna join with arcuate vein
big big peritubular capillary network is called vasa recta
efferent arteriole, gives off a branch that feeds deep down into the medulla and forms this capillary network, and this capillary network is called the vasa recta. It's very important for being able to concentrate urine
vasa recta has blood that can also drain into arcuate vein
So arcuate vein, blood from the vasa recta and the cortical radiated vein all dump their blood into this main moving down inbetween the lobes, so this main vein coming all the way down here
is going to be number 12 the interlobar vein.
the interlobar vein will feed into the renal vein and then go back to the inferior vena cava.
inside the Bowmans capsule 20, it's a little capillary network called the glomerulus.
glomerulus filters certain types of plasma components out of the blood and into the little like tubes here.
The membrane here that's surrounding it all the way around is called the Bowmans capsule
once the fluid that plasmas filtered to, it drains into this Bowmans capsule and then it goes into this like coiled tube. called proximal convoluted tubule.
proximal convoluted tubule goes down to the descending limp of the loop of Henle, and it comes back up to the ascending limb of the loop of Henle.
Then as it comes up back into the cortex, look, it starts getting coiled and is called the distale convoluted tubule.
Bowman's capsule,proximal convoluted tubule, descending limb,thin section, ascending limb, distale convoluted tubule.
The distale convoluted tubule dumps its filtrate the collecting duct number 6
Bowmans capsule, proximale convoluted tubule, loop of Henle and distal convoluted tubule makes up the nephron
renal corpusculum is the glomerulus and the Bowmans capsule
Now as the filtrate actually moving down the collecting duct, it'll get to the end of renal called the renal papilla,
there's a little duct portion here at the renal papilla called the papillary duct
And once its at the papillary duct, it's now urine
it drops off of the papillary duct of the renal papilla, and into that minor calyx.
renal corpusculum
It is the glomerus capillaries and the surrounding, it's called,Bowmans Capsule
Afferent feeds the glomerulus capillaries and efferent (7) drains the glomerulus capillaries
afferent arteriole have cells called JG-cells, or juxtaglomerularcells.
These juxtaglomerularcells are pressure-receptors.
They are baro-receptors and mechano-receptors and they can have the ability to sense changes in blood pressure and stretch.
When that happens, they have vesicules that they can secrete specific types of chemicals, like renin and renin helps to regulate our blood pressure
things in the back is a portion of the distal convoluted tubule.
distale convoluted tubule, have these specific cells, that are like chemo-receptors
I am SO thankful for your NINJA Nerd videos you have no idea 👩🏻⚕️
This helped me more than my entire nursing program. Thank you so much!
Best video of kidney anatomy
An excellent video. Crystal clear concepts now!
This video is awesome. Thanks for sharing your knowledge with us.
Notes 3/3
they pick up different chemical concentrations
These cells here are called the macula densa cells
juxtaglomerular-apparatus and it consists of the JG-cells in the afferent arteriole, and the macula densa cells in the distal convolute tubule,
glomerulus is this tuft of capillaries
and it's fenestrated capillaries
his is actually the raw capillaries here
theres this like beige tan covering on it
They're having cells clinging to the capillaries and forms the visceral layer of Bowmans capsule,
and this visceral layer of Bowmans capsule is these simple squamous cells, modified simple squamous cells they're called podocyts, which means foot cells
podocyts are clinging on to these glomerulus capillaries, and these are forming the visceral layer of the Bowmans capsule
outer layer out here, and whole out thing here is made up of simple squamous epithelial cells too,
but this whole outer layer here that's even continous with this actual podocyts visceral layer. This layer here is called the parietal layer of Bowmans capsule,
The podocytes make up the visceral layer of the Bowman capsule
and this outer part is the parietal layer of the Bowman capsule
Bowmans capsule is getting drained by this next structure, like little like simple cuboidal epithelial cells
called the proximale convoluted tubule. It processes a lot of different types of nutrients
and solutes and small proteins
afferent arteriole is consisting of the JG-cells,releasing renin that controls blood pressure, so they're baroreceptors,
efferent arteriole,
the macula densa cells, which are a part of the distal convoluted tubule they're like chemo-receptors
and then this whole area of the macula densa cells and the JG-cells is the juxtaglomerular apparatus
These cells are clining to the actual glomerulus capillaries, and is called podocyts they form the visceral layer of Bowmans capsule
The glomerulus capillaries are fenestrated capillaries very porous
and outer layer here is called the parietal layer of the Bowman Capsule,it's also very continous
with the visceral layer and then we have the proximal convoluted tubule down here, which is very important for absorbing specific types of nutrients, and for secretion of like, certains types of chemicals.
excellent class with wonderful information and clear explanation
Thank you sir 🙏🙏
You are helping me revising so easily 💜 thank you sir
I really love the way you teach the way you explain (love from India)
The video provides an in-depth look at kidney anatomy, detailing the layers of connective tissue that protect and cushion the kidneys, as well as the structure of the renal hilus and renal sinus. It also explains the blood flow through the kidneys, starting from the renal artery and branching into smaller vessels, ultimately leading to the nephron. The video covers key structures such as the glomerulus and Bowman's capsule, which are essential for filtration and urine production, highlighting their role in maintaining kidney function.
