Your heartbeat reacts to emotions instantly. 🎵😄😨

https://www.youtube.com/@DrBahaaDmour ────────── Your heart contains its own built-in nerve network (often called the “heart’s little brain”), and it constantly communicates with your brain through the autonomic nervous system. That’s why music, laughter, stress, or fear can change your heartbeat in real time. Even more fascinating: many heart muscle cells last for decades, meaning parts of your heart have been working since early life. And because the heart pumps under high pressure, blood can jet surprisingly far in extreme situations. ⚡🩸 ────────── 🎥 Video created by 🩺 Dr. Bahaa Dmour ⚡ CEO & Founder of Smart Doctor ────────── #Anatomy #Heart #HumanBody #3D_Anatomy #Anatomía #Anatomi #Anatomia #Education #Smartdoctor1 #Medicina #Doctor #Smart_Doctor #DrBahaaDmour #Dr_Bahaa_Dmour.
