. How do you account for the following differences


(a) The left ventricle has thicker walls than the right ventricle.

(b) The walls of the right ventricle are thicker than those of the right auricle.

 

Best Answer

(a) The left ventricle has thicker walls than the right ventricle because, the left ventricle pumps blood up to the farthest points in the body, such as, up to the toes in the feet or up to the brain against gravity. But right ventricle pumps blood only up to the lungs for oxygenation.

(b) The walls of the right ventricle are thicker than those of the right auricle because the right ventricle pumps blood up to the lungs for oxygenation. But auricles major function is to receive blood from the body and pump it into the very next ventricles.
