Thankyou!!!!!!!! For posting such helpful videos, currently a Respiratory Therapy Student. Again thankyou!!!!!thankyou for All that you do Sal Khan, i appreciate you and your team.......buckets of gratitude!!!
thanks for this video!! i was just wondering that in my school textbook it explains about lung diseases and how this has an effect on gas exchange. However in one part when explaining about emphysema it says 'inflammed alveolus/ bigger alveolus means there is less area for gas exchange to happen' why is this? surely if there was big alveolus thats a good thing ?
In emphysema the walls of individual alveoli break down, So the wall between two alveli break down leading to one 'bigger' alveolus but the total surface area decreases, as the wall provided more surface area.

I came to this video! :)
How do you comment on khan academy?
The exact pressure is 149.73
Ugh, comment sections always have obnoxious comments, just like yours...
I dont fucking get it how the fuck did he get 713 and you all arent asking questiions about it. wtf
He's almost right but his first equation is wrong
partial pressure in gases are calculated differently from partial pressure in liquids. His equations seem right to me :)
yeah he is right! sorry
