Human Heart Anatomy and Function

The video explains the structure and function of the heart, detailing the flow of blood through its chambers. It describes how blood enters the right atrium from the vena cavae, moves through the tricuspid valve to the right ventricle, and is pumped to the lungs via the pulmonary artery. After oxygenation in the lungs, blood returns to the left atrium through the pulmonary veins, passes through the mitral valve into the left ventricle, and is then distributed to the body via the aorta.
