@smart.doctor: @drbahaadmour - Four Valves, One Heart | See the System From Inside 🫀 ────────── Blood does not simply enter the heart and immediately leave—it follows a precisely controlled pathway through four chambers and four valves with every cardiac cycle. 🫀🩸 Oxygen-poor blood returns from the body to the right atrium, passes through the tricuspid valve into the right ventricle, and is then pumped through the pulmonary valve toward the lungs. Oxygen-rich blood returns from the lungs to the left atrium, passes through the mitral valve into the left ventricle, and is finally pumped through the aortic valve into the aorta and the rest of the body. The heart’s four valves act as one-way gates: they open when pressure drives blood forward and close to limit backward flow. This coordinated sequence allows the chambers to fill and eject blood efficiently from beat to beat. This 3D animation provides a close-up view of blood moving through the heart and shows how the chambers and valves work together as a single pumping system. 🔬 ────────── 🎥 Video created by 🩺 Dr. BahaaDmour ⚡ CEO & Founder of Smart Doctor ────────── #SmartDoctor1 #DrBahaaDmour #education #anatomia #Doctor #Anatomy #Anatomía #Anatomi #cardio #Medicina #HumanBody #3D_Anatomy #Education #BrainAnatomy #BrainHealth #HeartAnatomy #CirculatorySystem #cardiology #Pregnancy #Neuroanatomy
