Question

Quizplus · Accepted Answer

The accumulation of carbon dioxide in the body tissues leads to its release into the blood capillaries. The partial pressure of CO2 is higher in the pulmonary capillaries than atmospheric air, allowing for the exchange of gases to occur. The blood capillaries in the lungs release carbon dioxide into the alveoli, where it can be eliminated through exhalation.
