@smart.doctor: How the Heart Directs Blood: A 3D Anatomical View 💓 - - The heart is a precision-engineered pump that never rests. In this 3D anatomical visualization, we follow the exact journey of blood as it returns from the entire body, enters the heart, and is redirected toward the lungs and back to the body again. Venous blood from the superior vena cava (upper body) and inferior vena cava (lower body) flows into the right atrium. From there, it passes through the tricuspid valve into the right ventricle, which pumps it toward the lungs for oxygenation. On the opposite side, oxygen-rich blood returns to the left atrium, moves into the left ventricle, and is forcefully ejected through the aortic valve into the aorta, supplying every organ with oxygen and nutrients. This continuous, perfectly timed cycle happens about 100,000 times per day—without conscious effort. Quick Facts • The heart pumps about 7,000 liters of blood daily • The left ventricle has the thickest muscle wall due to high pressure • Heart valves act as one-way doors, preventing backflow • Blue blood is not truly blue—it simply carries less oxygen • A complete circulation cycle takes less than one minute Understanding this flow explains how life is sustained at the cellular level. - - 🎥 Video created by 🩺 (Dr._Bahaa_N_Dmour), CEO & Founder of Smart Doctor 🪄 - - - - #Anatomy #Smartdoctor1 #DrBahaaDmour #Dr_Bahaa_Dmour #Education
