ANATOMY

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: -Left Ventricle. The left ventricle is the main powerhouse of the heart, having to pump blood all the way around the systemic circulation. Because of this it has the largest, most muscular walls of any of the chambers. In fact, it is three times as thick as the right ventricle.

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.

Detailed explanation-4: -Final Answer: the left ventricular wall of the heart is thicker than the right ventricular wall to pump blood with greater pressure.

Detailed explanation-5: -Further, the left ventricle has thicker walls than the right because it needs to pump blood to most of the body while the right ventricle fills only the lungs.
