Why Is The Muscular Wall Of The Left Ventricle Thicker. It is because the left ventricle needs to pump blood to different parts of the body, and for this high pressure is applied by the wall of the left ventricle, which requires strength. When blood leaves the left ventricle it is propelled into the aorta(largest artery in the body) into the the left ventricle is thickest so it can accomodate the increased pressure and volume of blood that the thickness of wall muscles of these four chambers varies according to the pressure with which.
Ventricles are the lower two chambers, whereas the atria are the upper two when they contract, blood transfers from the atria to the ventricles, so the atria do not need to be as muscular as the ventricles.the ventricles of the.
Because the left ventricle needs to pump the blood further it needs to generate more force during contraction in order to do this. The muscular wall of the left ventricle is, for that reason, much thicker than that of the right ventricle. Left atrium → left ventricle → right ventricle → right atrium → lungs. These help in carrying blood away from the heart.
