As plasma PCO₂ increases,
A)hemoglobin synthesis increases.

D)respirations cease.

Question

Quizplus · Accepted Answer

As plasma PCO₂ increases, chemoreceptors in the respiratory center of the brain detect the change and stimulate an increase in ventilation to remove excess carbon dioxide from the body. This helps to maintain acid-base balance and prevent respiratory acidosis. Hemoglobin synthesis, vital capacity, and cessation of respirations are not directly related to changes in plasma PCO₂.
