Discuss the net diffusion of O2 and CO2 between the alveoli and tissues
What will be an ideal response?
Net diffusion of O2 occurs first between alveoli and blood and then between blood and tissues because of the O2 partial pressure gradients created by continuous replenishment of fresh alveolar O2 provided by alveolar ventilation and continuous use of O2 in the cells. Net diffusion of CO2 occurs in the reverse direction, first between tissues and blood and then between blood and alveoli because of the CO2 partial pressure gradients created by continuous production of CO2 in the cells and continuous removal of alveolar CO2 through the process of alveolar ventilation.
