Vedclass · Answer

(D) During rest,the metabolic activity of the body is at its lowest level. Since metabolic processes require oxygen $(O_2)$ and produce carbon dioxide $(CO_2)$,a decrease in metabolic rate leads to a reduction in the demand for oxygen and the production of carbon dioxide. To maintain homeostasis,the body adjusts its physiological parameters: $1$. The rate of breathing decreases to match the lower oxygen requirement. $2$. The pulse rate (heart rate) decreases to reduce the workload on the heart as less blood flow is needed for gas exchange. $3$. The overall $O_2$ intake and $CO_2$ output are minimized. Therefore,all these parameters are indicative of the body's metabolic state during rest.

During rest,the metabolic needs of the body are at their minimum. Which of the following is indicative of this situation?
