Vedclass · Answer

(B) As altitude increases,the partial pressure of oxygen in the atmosphere decreases. Consequently,as a man moves to a higher altitude,he receives less oxygen with each breath. This leads to a decrease in the oxygen saturation of the blood. In response to this low oxygen level (hypoxia),the respiratory center in the brain triggers an increase in the respiratory rate to compensate for the reduced oxygen intake. Simultaneously,the heart rate also increases to circulate the blood faster,ensuring adequate oxygen delivery to the tissues.
