WOW..... !!! you are the most an amazing teacher ever.....!!!!! THANKY SO SO... MUCH for doing this...!!! God bless you...! I wish you are my teacher...!!!!!:))))
Im nearly on my final unit for biology and every time I've come to watch your videos to help! You're such a great teacher, I'm taking you to uni with me!!
Thank you so much for this! There is just one thing I don't understand. You said diffusion keeps on going until the PP of O2 is the same outside and inside the lumen, same for CO2, but then how do they differ again for the next respiration cycle? Does exhalation makes them different again, if so how? Thank you!
I think that entire circle is a capillary as part of the microvasculature anastomosis of the lungs. Also, capillaries are the blood vessels incapable of constricting (blood flow controlled by arterioles and precapillary sphincters) and are only used for diffusion of oxygen and carbon dioxide and for tissues also nutrients and hormones. It is therefore not just the black area in the drawing since that area is definitely not the only site for gas exchange in that entire blood vessel.
Capillaries are also involved in thermoregulation. So the arterioles and the venules I think is only the part where the arrow points, not the circle at 8:23.
ur explanation always makes everything very easy. but why alveoli has pco2 40 mmHg. practically when we inhale we should inhale only oxygen. so alveoli has only oxygen. how alveoli has carbondioxide? pls let me know.
Why doesn't the blood leak into the lungs during the gas exchange ??? Is it because the holes are so small and the blood is too thick to leak into the capillary sac ???
The best explanation I have encountered. Absolutely perfect.
+Tiffany Kovacs thanks Tiffany
guys this guy just graduated med school in 2020 !! congratulations andrey !!!
THANK YOU SO SO MUCH!! I WISH YOU COULD BE MY TEACHER. GOD BLESS YOU EVERY DAY. YOU HAVE A GIFT TO MAKE SOMETHING SO HARD SEEM SO SIMPLE.
I got 100% in my quiz today. Thank you!
WOW..... !!! you are the most an amazing teacher ever.....!!!!! THANKY SO SO... MUCH for doing this...!!! God bless you...! I wish you are my teacher...!!!!!:))))
You're a really talented lecturer.
+Miles Holmes AMEN TO THAT MILES!
Im nearly on my final unit for biology and every time I've come to watch your videos to help! You're such a great teacher, I'm taking you to uni with me!!
Yet another excellent lecture. Thank you so much. This is very clear and understandable. God richly bless and keep you.
Thank you so much for all the work you put into your videos! U are a Legend!
i passed the medical boards with your lectures.. thankyou sir
Honestly the best teacher out there
I dont think you know how much this helps us..................and it's free ?? Thank you !!!
As usual your explanation is wonderful .
U r born to be an awesome teacher...great work sir 🤗🤗
thank you very much ur lectures are mind blowing I do really mean it.
God bless you for this videos. you are a savior
Grateful for finding your channel!!!
Best explanation,very detailed and organized.
you solve my problem to understand the difference between alveoli and alveolar sac
thank you from heart >3
It is just a great explanation .you are very talented, thank youu
Kindly bring more videos... ur way of explaining the things is amazing... thankyou..
I was trying to read this content on Berne las night and was almost a completely waste. You just saved me, tnhk u very much.

[13:07] do you mean pulmonary veins? Because what delivers oxygenated blood back to the left atrium is the pulmonary vein. You said artery.
I really want to meet you ...it could be online but really you're like a celebrity for me .... you're the king of white board videos
Wow...you are an awesome lecturer..
I don't know why you even have 27 dislikes. those people are dumb as hell dude. you the G.O.A.T.
Thank you ever so much for your lectures.
thank you so much ... you saved my life!
Thank you! I finally understand this concept.
Amazing. Video thanks very well explained
You're good at explaining. Wow
You are awesome i hope one day I could do videos as good as yours
Nice illustration!!
Love the explanation
Why is the PO2 in the alveolar space not 760mmg (1atm)?
thank you so much
This is awesome bro...
God bless you Dr AK thank you very much
Dr sir very satisfying lecture easy to understand thanks god bless you 11/02/2022
Best video!
good job man! God bless you
Is the basement membrane the same as the fused basal laminae ?
Luv from india..💓
you're a god damn hero, you need a cape.
thank you so much!!! youre really talented! wish you were my lecturer :(

Or is it? Lol.
should become a teacher
full understanding for us
You are the best!!!!

Thank you so much ☺️
So which one let's you maintain concentration gradient
1.What happens to the inhaled nitrogen?
2.The oxygen and carbon dioxide are diffused through the basement membare or the total of the cell membares?
Thanks in advanced
I was so anxious so as not to forget my questions that I forgot to thank you for your amazing video SORRY
is number 3 really the epithelium ?? someone correct me if im wrong....
Thank you!!
Why doesn't the blood leak into the lungs during the gas exchange ??? Is it because the holes are so small and the blood is too thick to leak into the capillary sac ???
I don't think there are holes as the gases are exchanged by being absorbed through the cells e.g. Epethelial cells
Very clear :)
12:16 from 105 down to 40, not 45 right?
Thank-You
12:20 from a value of 105 to 40mm Hg..so why you said 45 for partial pressure of oxygen
He just accidentally said that, what it says on the board is correct
13.06 connects with larger polmunary venuols
nice
he speaks like fred armisen in one of the mike's (fountain, busteria...) sketch
Wow 😎
Speed up to 1.25, you're welcome.
👏🏻👏🏻
Go to biomentors channel it is amazing for mbbs students
why is he looking down so often,,,,, ; )
