@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. For example, an LVEF of 64% means the left ventricle ejects 64% of the blood volume it contains at the end of filling, while about 36% remains inside before the next heartbeat refills it. A value of 64% is within the usual normal range. Blood then

The White House is proposing a major overhaul of U.S. research funding, shifting billions of dollars away from traditional university channels toward individual scientists and AI-driven tools. The plan argues that reducing bureaucracy could speed up scientific breakthroughs by giving researchers more direct access to resources. Critics are likely to question whether moving funds away from universities could weaken the institutions that support long-term research and training. #whitehouse #usa #n

@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
