Question

Which among the following is correct during each cardiac cycle?

• A. The volume of blood pumped out by the $Rt$ and $Lt$ ventricles is different
• B. The volume of blood pumped out by the $Rt$ and $Lt$ ventricles is same
• C. The volume of blood received by the aorta and pulmonary artery is different
• D. The volume of blood received by each atrium is different

Answer 1

The correct option is B

The volume of blood pumped out by the $Rt$ and $Lt$ ventricles is same

Explanation:

● In the simple circulatory pathway blood follows, in a way that the amount of blood ejected by the right ventricle ($RV$) must equal the amount of blood ejected by the left ventricle ($LV$). This will maintain a continuous flow of blood.

● Because , any amount of difference in volume pumped by $RV$ and $LV$, no matter how small, cannot be sustained. Thus, the correct answer is "the volume of blood pumped out by the rt (right) and lt (left) ventricles is the same".

Final answer

a. The volume of blood pumped out by the $Rt$ and $Lt$ ventricles is same.
