Role of Partial Pressure in Biological Systems

[405509920]

Partial pressure plays a key role in biology. In fact, without staying in an accepted range our bodies normally function at we aren't able to live. The most basic example being breathing. If the partial pressure is too low (like we see at high altitudes) our brain function is impeded, if you go high enough you won't be able to breathe all together. Are there any other examples of how partial pressure plays a role in our biology, or just biology in general?

Yes!

A great example is the heart pumping blood. Simply put, high blood pressure makes it more difficult to pump blood. The pumping of blood is driven by differentials in blood pressure. I can't explain it the best, but check out this article: https://www.uofmhealth.org/health-library/hw2343#:~:text=Partial%20pressure%20of%20oxygen%20(PaO2,the%20lungs%20into%20the%20blood.

Hope this helps :)
