Südamevatsikesest, also known as the cardiac ventricle, refers to one of the two large chambers located in the lower half of the heart. These chambers are responsible for pumping blood out of the heart. In humans and other mammals, there are two ventricles: the right ventricle and the left ventricle.

The right ventricle receives deoxygenated blood from the right atrium and pumps it to the lungs for oxygenation. The left ventricle, which is typically more muscular and powerful, receives oxygenated blood from the left atrium and pumps it to the rest of the body. The coordinated contraction and relaxation of these ventricles are crucial for maintaining blood circulation.

The walls of the ventricles are made of cardiac muscle, and their thickness varies depending on the workload they handle. The left ventricle's thicker wall is a testament to its role in propelling blood throughout the entire systemic circulation, a much greater distance than the pulmonary circulation served by the right ventricle. Valves, such as the tricuspid and pulmonary valves for the right side, and the mitral and aortic valves for the left side, ensure that blood flows in the correct direction through the heart, preventing backflow. The health and function of the ventricles are vital for overall cardiovascular health.
