@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

@Dr. Bahaa Dmour Inside Your Heart Chambers | Heart Valve Motion in Real Time 💓 ────────── 💓 S1 and S2 are the two main heart sounds heard in every normal cardiac cycle, and each one is produced by a precise valve event. In this animation, you will see how S1 is created when the mitral and tricuspid valves close at the start of ventricular systole, while S2 occurs when the aortic and pulmonary valves close as the ventricles relax and diastole begins. This high-precision medical animation gives

Heart lessons for student nurses. How the heart beats during (Preload, afterload) (S1, S2) (Lub, dub) (Diastole, systole) (P, QRS) The right hand represents the atriums and the left hand represents the ventricles. It is confusing to simultaneously move both hands so I try to move them separatelty. I hope this helps. Thank you for your understanding. #nursing #nle #nursinglecture #nursingreview #nursesoftiktok

Ever wondered what blood flow actually looks like in real time? 👀💉 In this clip, you can see a small cut underwater—and that pulsing you notice is the heartbeat pushing blood out in rhythmic waves. This happens because every time your heart contracts (a systole), it increases pressure in your arteries and capillaries. Even tiny vessels in your fingertips respond to that pressure change, so when the skin is opened, the flow becomes visible with each beat. Why underwater? 🌊 Water helps disperse
