Hydrostatic and osmotic pressure | Introduction to #edema

00:00 : Introduction to video
00:20 : Basic overview of fluid exchange at the capillaries
1:05 : Example and definition of edema (tissue swelling)
1:24 : Overview of fluid reabsorption in the capillaries.
1:38 : Definition of hydrostatic pressure (with an example! :D)
3:07 : Definition of osmotic pressure
4:43 : Definition of "colloid osmotic pressure" and "oncotic pressure"
5:12 : Putting it all together: how do hydrostatic and osmotic pressure drive fluid flow?
5:44 : Lymphatic vessels help reabsorb excess fluid

In this video, I'll show you how fluid is filtered out and then reabsorbed back into the capillaries. We'll review two central terms (hydrostatic pressure and osmotic pressure, also known as colloid osmotic pressure or oncotic pressure) to show these two dictate where and how fluid flows into or out of the capillaries. This process of fluid leaving and entering your blood happens all the time. However, when it doesn't go as planned, the tissue may experience edema or tissue swelling. We'll explain why.

I loved how you used the straw to explain the tissue hydrostatic pressure. All of a sudden, this thing makes so much sense. Thanks brother✊

[hamstereatingcarrots]

Finally i can visualize it 😭 great help

[psebfdo]

This is the best explanation available for these topics! Searched up all over YouTube but could not understand other explanations. Thank you so much for this! Truly the best!

[tasharice]

The way you explain it makes it so obvious and logical. I....understand it. I can't thank you enough.

I just passed my first test in grad school because of you (taking advanced physio). Just wanted to say thank you!!

[katherinelopez]

As I am studying for the MCAT, I am looking for videos that are straight to the point and your video did just that and more! Thank you. I will be looking at your other videos.

I LOVE this video!!! Finally understand osmotic and hydrostatic pressure after SO LONG of not getting it. THANK YOU!!!!

This is the best video on the internet explaining these pressures. Keep it up. Subbed!

[davidazinger]

physio flip you explain so well; the graph at 5:40 is genius Very helpful; thank you!!!!

[laurapeterson]

Thank you! I've been trying to understand this for over an hour for a paper, and this FINALLY makes sense!!!

[JohannaCoronel-bs]

Finally a short video, that is easy to understand. You got a new subscriber 😊.

[sajidikbal]

Now it’s totally clear to me....thanks.
Please make a video of movement of fluid across the glomerular membrane.

[ahmadhalholi]

This video helped me a lot thanks ❤
I don't know why good content in YouTube doesn't have too much views while bad and stupid content have millions

[DarkxAbsolut]

Probably the best science explanation I have seen ever in history. Thank you sir.

[kylapolk]

Thank you. You did a great job explaining this concept!

[eval]

That straw analogy is genius!! I just read that capillaries have pores in them and it fits perfectly with the straw analogy thank you!

[agustinmex]

2 years after your class and your stil teaching me stuf. Thanks profe

[rafaelreformado]

Thank you for saving my life tonight. I can’t understand the textbook and even the video provided by the e-book. Thank you so much!!

[meghasharma]

This was :) Thank you soo much ... I was trying to understand this concept for Glomerular Filtration rate. and now it is crystal clear.

[ssoz]

So osmotic, oncotic and colloids pressure was always the same😐😭
Very well explained thank you!
