The function of air sacs (alveoli) is to provide a large surface area for gas exchange
The more little sacs you have, the more surface area there is - and more surface area means more spots for oxygen to enter the blood system.
the more sacks the more surface area which means a greater surface area for oxygen absorbtion and CO2 excretion
It is to increase the surface area of the lungs so that more oxyen can be taken in.
The air sacs (alveoli) have a very large total surface area and a very good blood supply. There is an exchange of gases between the air sacs and their surrounding capillary blood vessels. Oxygen diffuses from the air sac into the blood. Carbon dioxide diffuses from the blood into the air sac.
Avioli increase the effective surface area which the body uses to transfer gasses to outside the body.
alveoli
because the oxygen needs to be diffused very easily and quickly aross the alveoli
Alveoli are the tiny air sacs that look like hollow plump grapes in healthy people. In emphysema, many of the alveoli collapse so there is less surface area for gas exchange.
To make room for millions, if not billions, of alveoli, small air sacs used to capture air to be dissolved into your blood.
Air sacs need a rich supply of blood vessels to facilitate diffusion. A large number increases the surface area available to pick up oxygen and get rid of CO2.
