The ventricles are the two lower chambers of the heart, known for their muscular walls that pump blood to the pulmonary and systemic circulations. The right ventricle pumps blood to the lungs, while the left ventricle pumps it to the rest of the body. They are not the same thickness; the left ventricle is thicker because it needs to pump blood to the entire body, requiring more force.
