The thick-walled inferior chambers of the heart that pump blood into the arteries are called ventricles.

The human heart consists of four main chambers: the right atrium, the right ventricle, the left atrium, and the left ventricle. The ventricles are the two lower chambers; specifically, the right ventricle pumps deoxygenated blood to the lungs via the pulmonary artery, while the left ventricle pumps oxygenated blood to the rest of the body through the aorta. The structure of the ventricles is crucial for their function, as they have thicker walls than the atria, enabling them to generate the high pressures required to propel blood into the circulatory system.
