Gas Exchange

[Mr.Smoke]

Dear Friends,
I do want to know the physiology of Gas Exchange which occurs in our Lungs.
Thanks

[rg]

actually it is a very complex process involving both lung,associated muscles and also hind brain....
explainin it would require a huge space....so it would be very helpful if u may ask about specific physiologies or process in mechanism of respiration....

I agree with rg , it would take alot of space to explain. here is a link i think pretty much sums it all up. > http://en.wikipedia.org/wiki/Gas_exchange < Hope you can figure it out from there. Feel free to bring up any specificities that are unclear.

[Mr.Smoke]

thanks, buddies.

Well, I do know that its really a big topic and it requires a huge space for demonstration, actually I wanna to get sum-up of gas-exchange in lungs.

actually this phenomenon includes participation of lungs, diaphragm and its associated muscles....when you inspire air in,the air is rich in O2 hence the partial pressure of O2 is much more in fresh air owing to which it diffuses into the blood through blood cappilaries after it gets soluble in the mucous layer of alveoli.......simultaneously the gas to be expired is rich in CO2 and hence the partial pressure of CO2(pCO2) is much more in the gas to be expired than the pCO2 in the alveoli.....hence it diffuses out into alveoli from blood through the capillaries and then expired out........i hope u got it....ask me any doubt u face here.....

thanx, yaar ( yaar=friend)
