Question

Quizplus · Accepted Answer

This statement is true. Systemic arterial P_CO2, which represents the partial pressure of carbon dioxide in the systemic arterial blood, is lower than tissue P_CO2, which represents the partial pressure of carbon dioxide in the tissues. This is because the tissues produce carbon dioxide as a waste product of cellular metabolism, which diffuses into the blood and is transported back to the lungs for elimination.
