Vedclass · Answer

(B) In the human respiratory system,the partial pressure of carbon dioxide $(pCO_2)$ in deoxygenated blood that reaches the alveoli is approximately $45\, mm\, Hg$.After the exchange of gases in the alveoli,the blood becomes oxygenated and the $pCO_2$ decreases to approximately $40\, mm\, Hg$.Therefore,at point $P$ (deoxygenated blood),$pCO_2 = 45\, mm\, Hg$ and at point $Q$ (oxygenated blood),$pCO_2 = 40\, mm\, Hg$.

In the given diagram representing the partial pressure of gases in the systemic circulation,what are the partial pressures of $CO_2$ at $P$ and $Q$ respectively? (Assuming $P$ is deoxygenated blood entering the lungs and $Q$ is oxygenated blood leaving the lungs)
