@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.

Euclid captures the Milky Way’s crowded heart ✨ This is the largest high-resolution photo ever made of our Milky Way galaxy’s centre in visible light.
