Question

Почему стенка левого желудочка более мощная ,чем правого желудочка?Почему стенки предсердий тоньше стенок желудочков

Answer 1

Левый желудочек так сказать большую работу ведь он выдавливает большее количество крови выбрасывая ее в аорту.

Answer 2

The Left Ventricle vs. the Right Ventricle

The left ventricle of the heart is generally more muscular and powerful than the right ventricle. This is due to the differences in their respective functions and the demands placed on them.

The left ventricle is responsible for pumping oxygenated blood to the rest of the body, delivering oxygen and nutrients to the tissues. It needs to generate enough force to overcome the resistance of the systemic circulation and maintain blood pressure throughout the body. To achieve this, the left ventricle has thicker and more muscular walls compared to the right ventricle.

The right ventricle, on the other hand, pumps deoxygenated blood to the lungs for oxygenation. The resistance in the pulmonary circulation is much lower compared to the systemic circulation, requiring less force to pump blood through the lungs. As a result, the right ventricle has thinner walls and less muscle mass compared to the left ventricle.

The Atria vs. the Ventricles

Similarly, the walls of the atria (the upper chambers of the heart) are generally thinner compared to the walls of the ventricles (the lower chambers
