NEET PG DENTAL EXAM

Detailed explanation-1: -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-2: -Explain why in the heart the wall of the left ventricle is thicker than the wall of the right ventricle? This is because the left ventricle pumps oxygenated blood round the entire body while the right ventricle only pumps blood to the lungs which is a much shorter distance.

Detailed explanation-3: -The wall of the right ventricle is thinner than that of the left ventricle because the right side of the heart pumps blood a shorter distance at lower pressure. Although the right side of the heart has a smaller workload, the right and left ventricle simultaneously eject the same amount of blood.
