Why is left ventricle has thick walls than right ventricle??

The left ventricle has thicker walls than the right ventricle because it is responsible for pumping oxygenated blood to the rest of the body, whereas the right ventricle only pumps blood to the lungs for oxygenation. The left ventricle needs to generate a higher pressure to push blood through the systemic circulation, so it has thicker muscle walls to support this function. Additionally, the left ventricle has a larger workload compared to the right ventricle, which also contributes to its thicker walls.

The left ventricle has thicker walls than the right ventricle because it pumps blood to the entire body, while the right ventricle only pumps blood to the lungs. The left ventricle must generate a higher pressure to push blood through the systemic circulation, which is a much larger and more complex network of blood vessels than the pulmonary circulation. The thicker walls of the left ventricle allow it to generate this higher pressure.

In addition, the left ventricle is responsible for pumping oxygenated blood to the body, while the right ventricle pumps deoxygenated blood to the lungs. Oxygenated blood is more viscous than deoxygenated blood, so the left ventricle must work harder to pump the same volume of blood. The thicker walls of the left ventricle allow it to overcome this increased resistance.
