Vedclass · Answer

(A) The left ventricle is responsible for pumping oxygenated blood to the entire body through the systemic circulation. To overcome the high resistance of the systemic circuit,it must generate significantly higher pressure compared to the right ventricle,which only pumps blood to the lungs (pulmonary circulation).Consequently,the muscular wall of the left ventricle is structurally adapted to be $2$ to $4$ times thicker than that of the right ventricle to withstand and generate this high pressure.Therefore,both the Assertion and the Reason are correct,and the Reason is the correct explanation for the Assertion.

$A$ : Left ventricle pumps blood at a much higher pressure to all body parts involved in systemic circulation.
$R$ : The muscular wall of the left ventricle is two to four times as thick as the wall of the right ventricle.
