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.

Which statement about infiltration is TRUE? Group of answer choices groundwater is an unsafe (dangerous) source of water not mea
weeeeeb [17]

Answer: Groundwater can remain in subsurface storage for long periods of time.

Explanation:

The ground water is the water reservoir that gets accumulated beneath the earth crust due to the accumulation of water that seeps into the soil and rock due to the absorption by water bodies river, lakes, ponds, oceans, and rain or any kind of precipitation. The groundwater remains as a subsurface storage of water until the site of groundwater is searched and water is extracted from it for household, agricultural or industrial purposes.
