How does the wall of the left ventricle differ from the walls of the right one?

Circles of blood circulation – small and large – begin from the ventricles of the heart in vertebrates. That is, the blood flows into the arteries. From the right ventricle to the pulmonary circulation, and from the left to the systemic circulation. The path along which the blood travels in a large circle is longer than the path traveled in a small circle. Therefore, the blood must have the maximum speed of movement through the arteries. To do this, it must be pushed out of the heart with greater force. Bottom line: the walls of the left ventricle are thicker than those on the right side.
