Vedclass · Answer

(B) At high altitudes,the atmospheric pressure is low,which results in low oxygen availability. To compensate for this,the human body undergoes physiological adaptations: $1$. The body increases the production of red blood cells $(RBCs)$ to enhance the oxygen-carrying capacity of the blood. $2$. The binding affinity of hemoglobin for oxygen decreases to facilitate the release of oxygen into the tissues. $3$. The breathing rate increases to intake more air. Since the question asks for adaptations to survive low pressure,increasing $RBC$ production is a primary response. Option $A$ is incorrect because hemoglobin affinity actually decreases to release $O_2$ more effectively at tissues. Therefore,only $B$ is the correct physiological adaptation.
