Hi! I am the heart, the most loyal and dedicated organ in every human being. Feet tired of walking to rest, hands tired of writing to put aside the pen, the brain tired to sleep, but only I, from the day it was formed in the mother’s womb, it will beat more than one, with you life and death. I lazy strike half a minute, people will be unconscious, stop breathing; I stop beating 4 to 6 minutes, it will lead to brain death. Knowing this, would you like to know more about me? Poke down!!! The following pictures will give you a 360-degree view of your heart from the inside out, from top to bottom!
