@drbahaadmourBlood Vessels on the Heart | 3D Anatomy 🫀 🔍 ────────── The heart pumps blood throughout the body, but its own muscle also requires a constant supply of oxygen and nutrients. 🫀 The coronary arteries arise from the aorta and distribute oxygen-rich blood across the myocardium. Cardiac veins then collect blood from the heart muscle, with much of it returning through the coronary sinus into the right atrium. This 3D anatomical view highlights the vessels running across the surface of

@drbahaadmourInside the Heart | Blood Leaves and Remains 🔄🫀 ────────── Your heart does not empty completely with every beat. 🔬 The left ventricular ejection fraction, or LVEF, measures how much blood the left ventricle pumps out during contraction.

A value of 64% is within the usual normal range. Blood then
