Vedclass · Answer

(B) In the human respiratory system,the partial pressure of gases in the alveoli is essential for gas exchange.According to standard physiological values:The partial pressure of oxygen $(pO_2)$ in the alveoli is $104 \, mm \, Hg$.The partial pressure of carbon dioxide $(pCO_2)$ in the alveoli is $40 \, mm \, Hg$.Therefore,the correct values are $O_2 = 104 \, mm \, Hg$ and $CO_2 = 40 \, mm \, Hg$.

Column-$I$	Column-$II$ (Amount of $CO_2$ in $mm \ Hg$)
$(a)$ Alveoli	$(1)$ $40$
$(b)$ Tissue	$(2)$ $45$
$(c)$ Blood without $O_2$ (Deoxygenated)	$(3)$ $40$
$(d)$ Blood with $O_2$ (Oxygenated)	$(4)$ $45$

What is the partial pressure (in $mm \,Hg$) of $O_2$ and $CO_2$ in alveoli?
