The human heart is a vital muscular organ located in the thoracic cavity, slightly left of the midline. It comprises four chambers:​ Right Atrium: Receives deoxygenated blood from the body.​ Right Ventricle: Pumps deoxygenated blood to the lungs. Left Atrium: Receives oxygenated blood from the lungs.​ Left Ventricle: Pumps oxygenated blood to the rest of the body.​ The heart also contains four main valves—tricuspid, pulmonary, mitral, and aortic—that ensure unidirectional blood flow. Understanding the heart's structure is essential for comprehending its role in circulatory health.
