Increasing the alveolar ventilation rate will Group of answer choices increase the partial pressure of oxygen in the alveoli. de
Pie

Answer:

Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.

Explanation:

Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.

A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli.  This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.

Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)

If the  alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.

If the  alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.

Vedmedyk [2.9K]
It should continue to be restricted. If it is not restricted, there is a chance it will become extinct. This not only has bad consequences for us, it destroys the food web as a trophic level is effectively eliminated.
