Detailed explanation-1: -The left ventricle pumps blood at higher pressures compared to the rest of the other heart chambers, as it faces a much higher workload and mechanical afterload. In comparison to that of the right ventricle, the free wall of the left ventricle is much thicker.
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.
Detailed explanation-3: -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-4: -The left ventricle, the most muscular chamber of the heart, then contracts with enough pressure to send the blood through the aortic valve and into the aorta. After the blood passes through the aortic valve it closes to prevent backflow of blood into the left ventricle.
