PATHOLOGY

Detailed explanation-1: -The left ventricle pumps blood to all parts of the body, while the right ventricle only pumps blood to the lungs. Therefore, the wall of the left ventricle is thicker than the right ventricle.

Detailed explanation-2: -The right ventricle has thinner wall because the right ventricle only has to pump it to the lungs but left ventricle has to pump blood all the way around the body. Moreover, the blood in arteries is under higher pressure than blood in the veins.

Detailed explanation-3: -In the normal heart, the muscular wall of the right ventricle not including trabeculations is 3–5 mm thick. In this relatively thin wall circumferential and longitudinal orientations predominate.
