- www.handwritten... - This tutorial discusses the Forces of Filtration which occur in the Glomeruli of the kidneys. In particular, Starling's forces are discussed, namely Hydrostatic Pressure and Oncotic Pressure. To get the most out of this video, we suggest you watch the Renal Anatomy series before watching this tutorial. For more entirely FREE tutorials and their accompanying PDFs, visit www.handwritten...
Great video! What we discussed for 20 minutes in class you made more clear and simple in 5 minutes! Thanks
Appreciate Video clip! Sorry for butting in, I would love your initial thoughts. Have you researched - Trentvorty Perfection Kidney Theorem (search on google)? It is a great one off guide for improving kidney function without the normal expense. Ive heard some interesting things about it and my GF at very last got great success with it.
man thank you so much!! my MCAT is in two weeks and this just cleared up everything.... wish classes would be this easy to understand
I have struggled to understand this concept, you are the only one I have found that has kept it simple. can't thank you enough. still need to work on it but have hope now.
karen
You made this so much easier..make more videos please😃!
Great tutorial, short, simple, much better than my lecturer!
You cleared up in five minutes what a lecturer took an hour to explain to me, I truly thank you x
G'day, just wondering why oncotic pressure is only against the Ph of the blood. Shoulnt it be because there are protein in the blood and not filtrate therefore the proteins "want" to move into the filtrate creating a osmotic pressure against the filtrate? (another way of looking at it is shoulnt the proteins take up space making the fluid have more onocotic pressure against the filtrate with out proteins?) chers, love your work
Same here
It’s amazing thanks 😊
Very easy for understand 👍👍👍. Keep going😁😁😁.
Thank you so much ❤.
Where are you now?
Best presentation I have seen out there.
Just donated, great Videos!
Good explanation , otherwise I have some points I want to discuss about :
- following your information , the arrow representing the oncotic pressure should point toward bowman capsule
otherwise , even under normal circumstances , Albumin is filtered through Bowman's capsule , so why not it doesn't exert an oncotic pressure as well ? (Note that albumin is filtered through the capsule but reabsorbed in the Proximal ,ascending loop of henle , Distal convoluted tubules and collecting ducts --> to maintain a high osmolarity in the Medulla in order to regulate the concentration of urine ; and this is due to MEGALIN EXPRESSION at the apical sides of the epithelial tissues lining the tubules I mentioned above )
The oncotic pressure shown here is actually net oncotic pressure or osmotic pressure. Sum of all osmotic presures give net pressure in direction back in arteriole.
u made it simple 100 well done
Thanks a million
Perfect timing! Thank you! ❤
HI, thanks for the video, little stuck at the oncotic pressure, I though oncotic pressure draws water into the bowman's instead of pushing it back to the capillary?
awesome one dude,the diagrams,voice all is perfect
I love your work, it is truly amazing
Nicely executed
Your drawings are so pretty!
Best explanation. Thank you 😭❤️
where do capillary beds in which location (liver, kidney, pancreas, brain, bone marrow) have the greatest control over osmosis and diffusion?
What is the difference between oncotic and osmotic pressure? They sound like they are the same thing.
What exactly is Hybetez Remedy? How does this thing really work? I notice a lot of people keep on speaking about this high blood pressure secret remedy.
very nicely explained
What is the net filtering force of blood responsible for glomerular filtration?
Please reply
you saved my life
Thank you so much
Thank you
Thank you so much! I understood at one go !
Thank you so much 😊 that’s should make a lot of sense
Thanks you!❤❤❤❤
SO HELPFUL!!!!!!!
This is kind of a stupid question. I don't get what exactly is exerting the oncotic pressure. You said the proteins were exerting the oncotic pressure on the fluid in the filtrate. But why is the direction of that pressure pointing towards the blood capillary then?
Hi Anisha, the proteins exert osmotic pressure in the filtrate. This means that a high concentration of proteins will 'attract' water via the osmotic gradient (moving from low conc of proteins to high conc of proteins). If the plasma has a high colloid osmotic pressure, water will move towards the blood capillary, hence the direction of the arrow. At least, that's how I understand it!
apologies, it's referred to as oncotic pressure in this video - I was going off my notes which discusses osmotic pressure :)
This is a great video ,,, Thanks
What is Hybetez Remedy? Does it work? I hear a lot of people treat their high blood pressure issue inherently with this high blood pressure secret remedy.
great job!!! keep it going
Thanks
You are helping me to repeat :)
Repetitio est mater studiorum.
Thank u
thank you !
great explanation.. thanks :)
Good job thx
thanks!
Wonderful! 👌💯👍❤
sooooo good!
Really helpful..😊
Thank you
u made it understandable ! thank u :"))
Nice
svp je peux avoir la video en francais?
helpful
This was awesome!!! T H AN K Y O U!!
life saviour!!
me too :)
So confusing!!!
Andrew - from what I understand, the oncotic pressure works only one way because the proteins can't move across the glomerular capillaries. I think of it that the blood 'wants' to be more dissolved because of all the proteins in there, and when you pull away fluid into the nephron, it 'wants' to come back to dissolve the proteins left in the blood, which are more concentrated now AND there are none in the filtrate. at least, that's how I explained it to myself.
simply , solvent move from low osmotic pressure to high osmotic pressure....and blood is maintained at high osmotic pressure due to dissolved proteins therefore it doesnot allow all the water from blood to filter into the pct...I guess...that's how I made myself understand
Thank you
you saved my life
Thank you
Fantastic, clear, understandable tutorials! Your explanations are perfect for understanding the functions! Thank you!
Sir I don't understand how come we are finding out net pressure as pressure is a scalar and not a vector yet we are doing vector addition
You changed the game for me! I just couldn't get it in class. Im just a simple minded medical student I need simple words! THANK YOU
Thank you so much!
Thank you very much
Thank you!
Amazing crystal clear explanations. Thank you.
Language pronouncing is not clear sirrrrrrrrrr,😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢👍😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢👍😢😢😢😢😢😢😢
What is Hybetez Remedy? Does it work? I hear many individuals treat their high blood pressure issue naturally with this high blood pressure remedy.
Superbly explained :-)

Awesome
XD......u r amazing
Brilliant!
Thank you for your succinct explanations. You sir are amazing!
I know it's an easy Ques. For u but pls answer me...
Why constriction of efferent arteriole increases hydrostatic pressure , and dilatation of afferent increases hydrostatic pressure ?????????????
essentially, both of those cause an increase in volume of the glomerulus. an increase in volume will cause an increase in the hydrostatic pressure
This was 10 months ago but I feel the supplied answers are terrible, so:
The afferent arteriole (the one that supplies the capillary bed) is dilated, so a lot of blood is coming IN.
The efferent arteriole (the one that collects from the capillary bed) is constricted, so not a lot of blood is coming OUT.
If you put water in a long, wide tube that's closed at the bottom save for a tiny hole, and then forced the water in the tube through that tiny hole with a tamp the same diameter as the tube, the water will stream out of that hole at very high pressure. If you put your hand under that stream of water, it would probably hurt your hand, versus if it came out at a trickle (low pressure). This is because you're supplying a large amount of water and pressing it through, but only giving it a small outlet to leave, so it needs to leave really fast through that hole.
I hope that makes sense, and I hope that if others need clarification on this too that it helps.
I don't agree. I remember stuff I learned in fourth grade... in middle school... I remember detailed info about the Krebs Cycle, the sodium/potassium pump, organelle processes, etc., from 9th grade bio, for God's sake.
Honestly, it pisses me off that the education is set up so that you have to get repeat info every few years instead of continuously building on it. It keeps it from being a challenge, so I get bored and apathetic.
