Which among the followings is correct during each cardiac cycle?
(a) The volume of blood pumped out by the Rt and Lt ventricles is same.
(b) The volume of blood pumped out by the Rt, and Lt ventricle is different
(c) The volume of blood received by each atrium is different
(d) The volume of blood received by the aorta and pulmonary artery is different
The answer is the option (a) The volume of blood pumped out by the Rt and Lt ventricles is same.
Explanation: After oxygenation, the volume of the blood entering the lung is the same as the volume of blood leaving it. In the case of varying volume, the heart is susceptible to heart failure due to different pressure.
