Decreasing the alveolar ventilation rate will No idea Paging

Decreasing the alveolar ventilation rate will No idea. Paging Lauren!

a) decrease the partial pressure of oxygen in the alveoli.

b) have no effect on either the partial pressure or diffusion rate of gases.

c) increase the rate of carbon dioxide diffusion from the blood to the alveoli.

d) decrease the partial pressure of carbon dioxide in the Alveoli. X Wrong!

e) increase the rate of oxygen diffusion from the alveoli to the blood.

Solution

a)decrease the partial pressure of oxygen in alveoli.

Alveolar ventilation rate is the rate of air flow in the gas exchange areas in lungs participating in normal breathing. Higher rates of air exchange in alveoli signifies higher alveolar ventilation rate and results in low partial pressure of co2 and high partial pressure of oxygen and vice versa.
