Solution

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.
