Detailed explanation-1: -The myocardium is thickest in the left ventricle, as the left ventricle must create a lot of pressure to pump blood into the aorta and throughout systemic circulation. Cardiac muscle has a high density of mitochondria and a large blood supply, which keep it functioning continuously.
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 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.
