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.
"Physio Flip" contains a semester's worth of physiology lectures, created by a physiology professor. I made this channel to help my students learn physiology on their own time, at their own pace. To help others do the same, I published my lectures.
This channel is dedicated to helping students and instructors navigate physiology by providing full access to a semester's worth of physiology videos. Some videos are entire lectures while others are one part of a lecture. You can follow through the video series in order by following the numbers that are in each video title. For instructors interested in using these lectures to "flip" your course, please contact us!
