For a lot of us who were bullied, it took a lot for us to finally accept and be confident with our height and for y’all to sit on this app and try to exclude us is crazy #tallgirl #meangirls #xyzbca #fypシ

Inside the Heart in 3D | Blood Flow Through the Four Valves 🫀 ────────── The human heart contains four valves that open and close in a precise sequence to maintain one-way blood flow. 🫀 In this 3D animation, the tricuspid valve directs blood from the right atrium to the right ventricle, the pulmonary valve leads it toward the lungs, the mitral valve guides oxygen-rich blood into the left ventricle, and the aortic valve sends it into the aorta for systemic circulation. This valve timing is what prevents backward flow and keeps cardiac output efficient with every heartbeat. The video also reveals the spatial relationship between the chambers, the valve leaflets, and the major vessels above the heart, including the aortic arch and pulmonary outflow tract. 🔬 A detail many viewers miss is that the semilunar valves, aortic and pulmonary, do not use chordae tendineae like the atrioventricular valves, mitral and tricuspid. Instead, their shape and pressure gradients help them close effectively during ventricular relaxation. This view turns complex cardiac anatomy into a clear visual pathway for students, educators, and anyone trying to truly understand how blood travels through the heart. 📚 ────────── 🎥 Video created by 🩺 Dr. Bahaa N.
