The partial pressure of carbon dioxide in systemic arterial blood is the partial pressure of carbon dioxide in systemic arterial blood is 100 mm hg 40 mm hg 104 mm hg 45 mm hg

In the systemic arteries, the partial pressure of carbon dioxide is  40 mm Hg.  Partial pressure of a gas is the contribution of one gas to the total pressure exerted by all gases. Partial pressure of carbon dioxide in arterial blood is the portion of total blood gas pressure that is exerted by carbon dioxide. It decreases during heavy exercise, during rapid breathing, or in association with severe diarrhea, uncontrolled diabetes or the diseases of the kidney. It increases with chest injuries and respiratory disorders. In the systemic arteries, the partial pressure of  oxygen is 100 mm Hg.
