Vedclass · Answer

(A) Under normal physiological conditions,every $100 \,mL$ of oxygenated blood can deliver around $5 \,mL$ of $O_2$ to the tissues. However,the venous blood returning to the heart still contains a significant amount of oxygen (about $75\%$ of the original saturation). This residual oxygen acts as a vital reserve that can be utilized by the body tissues during periods of high metabolic demand,such as intense muscular exercise,when the oxygen requirement increases significantly.

$A$ large proportion of oxygen is left unused in the human blood even after its uptake by the body tissues. This $O_2$
