What keeps blood flowing in the right direction with every heartbeat? 🫀 The answer lies in four remarkable heart valves working together as a one-way system. The human heart contains four valves: the tricuspid, pulmonary, mitral, and aortic valves. Each plays a vital role in maintaining efficient blood circulation and preventing significant backward blood flow. 🔬 HOW THE FOUR HEART VALVES WORK 🔹 Tricuspid Valve Located between the right atrium and right ventricle, it allows blood to enter the right ventricle and closes during ventricular contraction to prevent blood from flowing backward into the right atrium. 🔹 Pulmonary Valve Positioned between the right ventricle and pulmonary trunk, it opens when the right ventricle contracts, allowing blood to travel toward the lungs. It closes as ventricular pressure falls, preventing blood from returning to the ventricle. 🔹 Mitral Valve Located between the left atrium and left ventricle, this two-leaflet valve allows oxygen-rich blood to fill the left ventricle. During ventricular contraction, it closes to prevent blood from returning to the left atrium. 🔹 Aortic Valve Situated between the left ventricle and aorta, it opens during ventricular systole, allowing oxygen-rich blood to enter systemic circulation. It closes during ventricular relaxation to prevent backflow into the left ventricle. 🩺 THE HIDDEN SUPPORT SYSTEM The tricuspid and mitral valves are supported by chordae tendineae, strong fibrous cords connecting their leaflets to papillary muscles inside the ventricles. During ventricular contraction, the papillary muscles contract and maintain tension on these cords, helping prevent the valve leaflets from prolapsing into the atria. Unlike the atrioventricular valves, the aortic and pulmonary valves have three semilunar cusps and do not require chordae tendineae or papillary muscles. ⚠️ WHY VALVE HEALTH MATTERS When a valve becomes narrowed (stenosis), blood encounters increased resistance. When it fails to close properly (regurgitation), blood leaks backward. Either condition can place additional strain on the heart. This detailed 3D heart anatomy animation reveals the internal structure of the cardiac chambers, heart valves, chordae tendineae, papillary muscles, and their anatomical relationships. ────────── 🎥 Video created by 🩺 Dr. Bahaa N.
