I hope you read my comment! I just wanted to let you know I have been using your videos since I entered college, and I am about to graduate and start medical school this summer. I swear if it wasn't for you, I wouldn't have done well on my MCAT or have a 4.3 GPA. THANK YOU SO SO SO MUCH!!!
Intercostal not Intercoastal ribs but overall great videos, great teacher, great presenter. Thank you for all you do! Learned a lot from your various videos!
you said that intrapleural pressure become positive and then exhailing starts, but i thought that intrapleural pressure become positive only in forced exhalation, and in normal breathing IP pressure always less than atmospheric(or alveolar) but more or less "negative"
I always thought that exhaling RELEASES the pressure, and inhalation increases pressure (just by going by how we feel...)... I heard from class that EXHALATION is actually high pressure because of the "air being pushed out" (you also just said this towards the end).. I thought of it kind of like the ventricles pushing out blood, it has higher pressure as opposed to when it's relaxed when it's being filled. So, which type of ventilation is high pressure in the lungs and which is low? (and everywhere else that's involved?)
Also I can't understand this: I thought our respiratory muscles contracted because of the air being inhaled, from your lecture it seems that the muscles contract and THEN the air flows in (after the muscles contract), is this correct? Also how can inhalation decrease the pressure inside the lungs? It's true that inhalation expands the volume, so by Boyle's law the pressure should decrease but inhaled air is made up of different molecules, shouldn't these molecules increase the pressure? Where am I getting this wrong? Please help ç_ç Thank you very much!!
I can't understand how can the intrapleural pressure play such an important role if it's a closed space that has no connections with the outside environment ç_ç
the intrapleural space has serous fluid that is constantly removed by the lymph system and this creates a vacuum keeping the lungs from collapsing, normally the P inside the space is at 4mmHG but I think he got confused between the two spaces he actually meant to say intrapulmonary

Venes Barlas 4.3?
ibro khan not all countries have 4 gpa, it depends on countries, in India it is out of 10
Thanks! This helped me with my Med Exam.
I have never understood that expression "negative pression" !!! Now it is clear! Thank you Sir!

Thank you. What helped was the pressure in the lungs is the same atm.
I like how you explain negative pressure it was amazing .

Sir your lectures ubspired me too much I learned alot from your lectures
awesome! so great! Please keep making these videos!
Tricia Leftwich Thanks Tricia! will do :)
Very good, love your videos.
This is awesome sir you are doing very good you
at this point, youre teaching me physiology, not my professor. lol thank you i appreciate you so much
thank you very much .very clear explanation.

Nice Sir u r the best
Thank you 😊 but we need to see how nots is, is too small so it hard to see it
Loved it 💜💕
awesome.sir
Thanks a lot😄😄

Wow thanks ,
Woow thnx so much .
awesome 6 years later
nice

Hello sir
I can't understand how can the intrapleural pressure play such an important role if it's a closed space that has no connections with the outside environment ç_ç
GoodbyeRubyTu3sday I have the same question. Did you manage to find an answer?
the intrapleural space has serous fluid that is constantly removed by the lymph system and this creates a vacuum keeping the lungs from collapsing, normally the P inside the space is at 4mmHG but I think he got confused between the two spaces he actually meant to say intrapulmonary
wow
