Meet the Kidneys - those fist-sized organs that are shaped like beans. They are kind and hardworking organs located in your upper abdominal area, attached to the back of the abdominal cavity on either side of the vertebral column.
Your kidneys have 4 important roles, so luckily we have two of them!
1. Regulate water
2. Remove waste products
3. Balance minerals
4. Produce hormones
They are essential for excretion, cleaning your blood everyday as it passes through them, by removing urea and other chemicals
However, sometimes your kidneys may fall sick.
This may be self-inflicted, such as drinking excessive amounts of alcohol or taking drugs, or might occur as a result of other illnesses, such as diabetes or experiencing severe injury that leads to a bacterial infection. This can cause kidney failure, which is when your kidney cannot function properly anymore, leading to a build-up of waste products in your body.
As you can imagine, these waste products are dangerous, and them staying in your body for too long can cause serious damage. To help relieve the kidneys of this duty, patients can undergo dialysis for about four hours, three times a week. So, what happens during dialysis?
Patients sit in chairs much like lounge chair.
A needle is inserted into the patient’s vein and untreated blood starts flowing into the dialysis unit.
Let’s follow this blood to see how it gets cleaned:
• A pump pushes the blood through the dialysis tubing, which is partially permeable to ensure that large particles like blood cells and proteins cannot leave the tubing.
• The tubing is suspended in dialysis fluid, or dialysate.
• Dialysis fluid is a special solution of pure water, electrolytes and salts. It contains no urea or waste products.
• No waste in the dialysis fluid means as the blood flows through the tubing a concentration gradient is created, allowing waste products to be removed from the blood and into the dialysis fluid by diffusion.
• The dialysis fluid also contains electrolytes and salts to help correct any other imbalances in the blood, that may have arisen from the kidney failure. Also making use of concentration gradients and diffusion.
• Sometimes glucose is also included in the dialysis fluid, either to remove excess fluid from the blood or to provide the blood with more glucose if it’s lacking.
• Once the blood is thoroughly filtered and cleaned, it returns to the patient through their artery.
• The used dialysis fluid is then disposed of.
While dialysis can replace the work of a failed kidney, it can very uncomfortable and time-consuming. For this reason, some people instead opt for Kidney Transplants. However, while these prove to be a much better long-term solution, as you will not have to eat a restricted diet or experience any discomfort, they tend to be very expensive and finding a matching donor tends to be very difficult.
Even if both conditions are met, you still might be at the risk of your body tissues rejecting the transplanted kidney which will require you to take immunosuppressive drugs. So, remember to take good care of your kidneys as they help keep your body clean and healthy!

0:13 that voice crack though i can’t
bruh lmaooooo are u serious rn
lol I had to go back and listen ROFL you dumb lol
plus, you missed one point i guess. When passing the blood from the dialysis back into the person's body you must correct the temperature into the body temperature. So that the person won't get any brain shocks etc.
anyways loved your video:))
Great video - super useful for everyone doing gcse biology!
Glad you think so!
For Igcse aswell
1:16 Got em
Really...?
Great spot!!!
👌
Great video
ILY FOR THIS
Thank you so much sir for teaching me
Always happy to help!
learning this during quarentine :D
ya
nelllllllyyyy
sane lol
Army ?
wowowowoww super amazing explaination thanku so much
Most welcome 😊 glad you liked it!
Ty for everything
Most welcome 🤗
HOLY SHEEEEEEET! this was on another level tbh, i lOvEd this video and its animations , please dont stop making more! Also, how is urea produced?
Thanks! Glad you liked it 🙂
Here are two articles you may find useful:
sciencing.com/urea-made-5194345.html
www.ch.ic.ac.uk/rzepa/mim/environmental/html/urea_text.htm
it's the excess amino acids that form urea and it'e extremely toxic
Like it's Soo simple bro, excessa mini acids gets deaminated to for ammonia in the liver combining with CO2 forming urea. Bro it's like the easiest thing ever, how come you don't know this
Now i now something about kidney disease thank you for that video
You're most welcome!
Great Video!!! I have a project on kidney dialysis and this helped alot!
Glad it helped!
You’re teaching skill very good
Thank you!
Sooooooooooo good explanation 😮😮😮
Glad you liked it!
My exams are coming and this helped a lot
Awesome! Glad it helped. Good luck with your exams!
I am 7 th I love learning biology
Nice explanation
Thank you!
You have the abdominal aorta and the vena cava backwards. The abdominal aorta runs down on the left side of the vertebral column and the vena cava runs up the right side of the vertebral column. The left kidney has a longer renal vein which is why its optimal for transplantation.
Good point. Thank you!
@@fuseschool 。
Very cool video
Thanks!
Great videooo
Thank you!!
A part of the video says that Kidneys produce hormones? Which are those hormones, could someone explain please?! Thank you :)
👍👍
Epic
I agree, Mr Hi There (If that even IS your real name!!?)
So human can create artificial kidney
The VIDEO is really very helpful..Thanks!!
You are welcome!
really awesome video i understand every part of it, however, it would be best if the music would be played much lower than that because i keep focusing on the music rather than the video itself!
Thanks! And noted!
WOW
ok
1st needle is inserted into artery not vein.
Which program do you use for your videos? They are pretty nice
Thanks! We use After Effects.
Full process of kidney failure . Make full explanation of kidney failure
how do u know that my kidney is kind?
Vein to artery?
I am at school 👌
sir as you mention blood is taken from vein, but as per text book blood should be taken from artery for dialysis
Yes
El aula de Biology. O miento?
One month than agudu ... Hand la vain kidakala so throat la tube potruku pray my mother
can i use this video for my documentary assignment? i will mention your channel at the credits section at the end of the documentary..
Sure! Please, email us to find out what the requirements are to use our videos.
my biology gcse is tomorrow lmao
I'm a A+ kidney donar
First
Amma ku idha problem than dialysis paniturukom
Kidney plays an important role in keeping the whole body clean, well-fueled, strong and functioning properly. Kidney failure puts the body at risk, allowing waste to accumulate and damage the kidneys from inside. It is a good idea to do a kidney cleansing and keep a check on the health of the kidneys in your middle and old age. The toxins that buildup results in nausea or feeling sick to the stomach, lack of concentration and blood pressure changes are all symptoms of kidney failure.
I'm Muslim, and this video made me really happy! because in Quran (the holy-book) 1500 years ago, Allah (god) prevented us from drinking alcohol, and says that it's bad for us!
in 0:37 you said kidney disease could be a result of drinking alcohol !!
isn't that crazy that this info was mentioned 1500 years ago in Quran!!

Pe teacher part???????
Ur.. wrong
