In a healthy person, the partial pressure of carbon dioxide (pCO2) in systemic arterial blood is equal to the pCO2 in the alveoli.
Question
In a healthy person, the partial pressure of carbon dioxide (pCO2) in systemic arterial blood is equal to the pCO2 in the alveoli.
Solution
This statement is generally true. In a healthy person, the partial pressure of carbon dioxide (pCO2) in systemic arterial blood is approximately equal to the pCO2 in the alveoli. This is due to the efficient gas exchange that occurs in the lungs.
Here's a step-by-step explanation:
-
When you inhale, air fills your lungs and comes into contact with the alveoli, tiny air sacs where gas exchange occurs.
-
Oxygen from the inhaled air diffuses across the thin walls of the alveoli and into the surrounding blood vessels, where it binds to hemoglobin in

What are the partial pressures of oxygen and carbon dioxide in blood traveling via systemic arteries to tissues?Multiple ChoicePO2 = 40 mmHg and PCO2 = 45 mmHgPO2 = 95 mmHg and PCO2 = 40 mmHgPCO2 = 104 mmHg and PO2 = 40 mmHgPO2 = 95 mmHg and PCO2 = 75 mmHg
The partial pressure of CO2 is in the atmospheric air compared to the partial pressure in blood.
8) Ventilation–perfusion inequalities lead to hypoxemia becausea) the relationship between PCO2 and the content of CO2 in blood is sigmoidal.b) a decrease in ventilation–perfusion matching in a lung region causes pulmonaryarteriolar vasodilation in that region.c) increases in ventilation cannot fully restore O2 content in areas with lowventilation–perfusion matching.d) increases in ventilation cannot normalize PCO2.e) pulmonary blood vessels are not sensitive to changes in PO2
