Thank you for great explantion ,just if you can explain the concept of transpulmonary pressure and cardiac trans mural pressure ,how are they connected thanks
Hi! Thanks for the comment! However, the intrapleural pressure at the bottom is greater than the intrapleural pressure at the top when a person is standing. This is because when a person is standing, gravity pulls the lungs down from the apex toward the diaphragm. This creates a greater partial vacuum at the apex than at the diaphragm. This is why the intrapleural pressure at the apex is more negative than the intrapleural pressure at the bottom when a person is standing. And since the intrapleural pressure at the apex is more negative than the intrapleural pressure at the bottom, this means that the intrapleural pressure is less than that of the base.
A less negative number is larger/greater than a more negative number. Just because the number itself is smaller should not distract us from the fact that there is a negative sign in front of both values. Therefore -2.5 for example is a much greater pressure than -10
This is the most accurate and easy explanation for this topic ….. finally understand the concept
Man you made it like a piece of cake, thank you so much
Superb! Explained so so clearly! Can't believe I've finally understood this. Thank you so much! 👏🏾👏🏾👏🏾🙌🏾🙌🏾
Thank you for your kind words! I'm glad this video helped!
Thank you for great explantion ,just if you can explain the concept of transpulmonary pressure and cardiac trans mural pressure ,how are they connected thanks
thank you continue you are smart
Helpful
Thx
You said it the opposite way...the pressure at the bottom is greater than the top?? I think you mean the other way around.
