Heart

Chambers of the Heart

The four chambers of the heart - left atrium, right atrium, left ventricle, and right ventricle - that play essential roles in the cardiac cycle.

Valves of the Heart

Tricuspid, pulmonary, mitral, and aortic valves that ensure blood flows in the correct direction, preventing backflow and maintaining the heart's pumping efficiency.

Blood Vessels

Aorta, pulmonary artery, pulmonary veins, and vena cavae that facilitate the exchange of gases and nutrients by transporting oxygen-rich and oxygen-poor blood to and from the heart.

Conduction System

The SA node, AV node, bundle of His, and Purkinje fibers that coordinate the heartbeat, regulating the heart's rhythm for synchronized contractions and efficient blood circulation.
