الحمدلله Matched into ENT. Extremely grateful for the opportunity #matching2026

At 14 i moved from England to the KSA, i spoke no Arabic and struggled to integrate. I would be told i had no future as i could not speak the language. Today, at 25, i have graduated medical school with honors. الحمدلله #تخرج_JU2025

3. Conductivity system The heart possesses it’s own pacemaker (SA node) which generates impulses that don’t rely on any stimuli, and a conduction system that has different resistances at different areas to ensure the chambers beat in a specific rhythm - the sinus rhythm

2. Compensatory mechanisms -the heart muscles are layered in a way that adjusts the force of contraction in response to blood volume entering the heart by stretch (frank-starling)

1.Mitochondrial density Due to the huge workload of the heart, the cells are equipped with massive amounts of mitochondria (40% of cell) for energy for contraction. These mitochondria are strategically placed near the contractile elements to allow efficient energy transfer

The perfect “design” of the heart 🫀 This small thread aims to provoke thought in those who believe life was built on coincidence while exploring the intricate design of the heart which helps it fulfill its crucial role🧵🧵🧵 (1/11) #atheism #NoDesign #Medtwitter

Electron microscopy of the human glomerulus, showing all the tiny slits for precise filtration, and they still say #NoDesign 😂
