The significance in thickness between the two is due to the different amount of pressure exerted on the walls of the heart. The left ventricle has a thicker wall because the blood must be pumped throughout the entire body (oxygenated blood), unlike the right ventricle, where blood is pumped simply to the lungs to be oxygenated (pulmonary system).
