@smart.doctor: The Heart’s Own Blood Vessels ❤️ ────────── 💓 Your heart beats about 100,000 times a day—and most people never realize that the heart muscle itself gets its blood supply mainly during relaxation (diastole), not during the squeeze. 🫀 Quick facts you’ll remember: • Atria and ventricles are electrically insulated—normally, only the AV node connects them. ⚡ • Heart cells are loaded with mitochondria because the heart depends on oxygen 24/7. 🔋 • Valves have minimal direct blood supply, so degeneration/calcification is a big deal. 🫀 • The heart also acts like an endocrine organ (ANP/BNP) that influences blood pressure. 🧪 ────────── 🎥 Video created by 🩺 Dr. Bahaa Dmour ⚡ CEO & Founder of Smart Doctor @drbahaadmour ────────── #Anatomy #Heart #Smartdoctor1 #DrBahaaDmour #cardio #anatomia #education #anatomi #heartanatomy #medicina #3danimation
