Answer :
1. The gas whose concentration decreases when pCO2 levels increase in order to maintain oxygen levels is nitrogen.
2. Minute ventilation is the total volume of air that is breathed in and out in one minute.
3. CO2 and pH have a direct relationship that affects minute ventilation.
4. Inhaling increased amounts of CO2 can affect pulmonary ventilation in a number of ways. The increased levels of CO2 can cause the respiratory rate to increase, leading to hyperventilation.
1. The gas whose concentration decreases when pCO2 levels increase in order to maintain oxygen levels is nitrogen. As the amount of CO2 in blood increases, the body compensates by decreasing the concentration of nitrogen gas in the inhaled air.
2. Minute ventilation is the total volume of air that is breathed in and out in one minute. When inhaled air contains 5% carbon dioxide, minute ventilation will increase to help remove the excess carbon dioxide from the body.
3. CO2 and pH have a direct relationship that affects minute ventilation. When CO2 levels increase, the pH decreases and causes the respiratory rate to increase. This increased ventilation helps to remove excess CO2 and restore the pH balance.
4. Inhaling increased amounts of CO2 can affect pulmonary ventilation in a number of ways. The increased levels of CO2 can cause the respiratory rate to increase, leading to hyperventilation. This can cause dizziness, shortness of breath, and other symptoms. Additionally, it can lead to respiratory acidosis if the body is unable to compensate for the increased CO2 levels.
