Your heart, the hub of your circulatory system, ensures oxygen-rich blood circulates throughout your body. Situated centrally under your breastbone and tilted left, it’s shielded by your ribcage.

Functioning in tandem with other systems, your heart regulates blood flow, heartbeat rhythm, and pressure. Controlled by the nervous system and hormones, it adjusts pace and vessel dilation.

Alpine Cardiology - Heart AnatomyThink of your heart as your dwelling: chambers are rooms, valves are doors, vessels are plumbing, and its rhythm is electrical. With four chambers—two atria and two ventricles—separated by the septum, it orchestrates blood flow.

Starting with the right atrium, blood enters via the vena cavas, flows through the tricuspid valve to the right ventricle, then to the lungs via the pulmonary valve and arteries for oxygenation. Returning via the pulmonary veins, oxygen-rich blood enters the left atrium, proceeding through the mitral valve to the left ventricle, then out to the body via the aortic valve.

Your heart’s walls, comprising the endocardium, myocardium, and epicardium, enable contraction and protection. Encased in the pericardium, it’s shielded and lubricated, ensuring smooth function.

Four valves—tricuspid, pulmonary, mitral, and aortic—regulate blood flow, maintaining the heartbeat rhythm. Arteries carry oxygenated blood, veins return it, and capillaries facilitate exchange. Nourished by coronary arteries, your heart’s electrical conduction system, coordinated by nodes and fibers, controls heartbeat pace and rhythm.

Remember, your heart’s health reflects both physical and emotional well-being, influenced by lifestyle and diet. Prioritize holistic wellness for a healthy heart.
