You're an amazing instructor! Explained the concepts easily, enthusiastically, but also added important caveats that really solidify my understanding! Thank you
I just learned more about Starling's law of the capillaries from this video than from my lecture class. Thank you for putting the time into making this video!
Thank you so much. It's clear for a non-native speaker as me. Somehow it helps perfectly on my understanding about the inflammation process in the pulp cavity. Thanks! from Viet Nam
I'm not a native speaker and although I usually don't have any trouble understanding what's being said, I sometimes have a hard time "feeling" the topic since the language just doesn't feel 100% natural. But your way of explaining things is somehow just perfect for me, you're so easy (and dare I say fun or is that weird because we're trying to learn something here? :p ) to listen to! This is perfect for me, thank you.
I really appreciate your video!!! I'm currently taking an online A&P course and there's no lecture time. This video really breaks everything down and I like that you mentioned oncotic pressure and instead of colloid solution it's technically molecular Thank you for taking the time to share this!
Wow this video was so helpful. Best explanation of oncotic/osmotic and hydrostatic pressure in relation to the capillaries I've seen so far. Thank you!
OMG....LOVE THIS VIDEO SO MUCH REALLY HELPS...PRENURSING STUDENT WITH 3KIDS STUCK IN HOME DURING THIS PANDEMIC ..CAN CAUSE FOR EXTRA HELP..ALL ONLINE CLASSES SO THIS VIDEO REALLY HELPS.. SOMETIMES THESE CONCEPTS CAN BE TRICKY BUT HELPS WHEN U HAVE FULL KNOWLEDGE ..THANKS SO MUCH
This video saved my life!! thank you so much you did an awesome job! keep up the great work!!!!!! also you have a lovely voice unlike my teacher who is so monotone and boring.
Thank you for this. Can you do video with starlings principle updated to show that in fact it's a net filration out of the capillaries and not reabsorption? Compare and contrast? Thank you!
Hey, great video! Finally understood how the capillary microcirculation works. Just one doubt though: interstitial colloid pressure tends to bring fluids from the capillary toward the interstitium while interstitial hydrostatic pressure bring fluids inside the lymphatic system? Thank you in advance :)
This was such a great help! Thanks for clarifying my IB Biology doubts. I do have a question. It wasn't clear to me how exactly the lyphatic system keeps the interstitial hydrostatic pressure at about a 0.
Thank you for the excellent presentation, I wonder ,however, about the kinds of physiological changes that would occur at within such a space if a lateral force of negative pressure were applied over these tissues from the outside as happens during dry cupping..some estimate that a negative vacuum between -150 and 450mmhg may be created...I will be most grateful if you consider my request for an explanation
Ah I still don't get what oncotic pressure is - everywhere it is mentioned that it is the pressure exerted to PREVENT any more water absorption - what does that mean exactly, what exerts that pressure? It implies the two different solutions must already attain some sort of equilibrium just like in that sugar water example. Thank you!
awesome vid. so since RBCs, WBCs and plasma proteins can't leak thru, is it fair to assume something like a histamine or prostaglandin is going to affect the oncotic pressure since prostaglandins/histamines increase cell wall permeability, thus allowing the bigger molecules to leak thru, and therefore increasing oncotic pressure?
+oopalonga Yes, it depends on the local milieu, and generally anything that increases capillary permeability and promotes movement of WBC out of the vasculature and into the tissue will increase the interstitial oncotic pressure
