Hi guys, my name is Dr. Mohammadreza Ghasemi.
I am an Iranian Veterinarian who is studying Psychology at Mykolas Romeris University
in Lithuania at the moment, today we are going to talk about heart and how it actually
works in simple words.
Hope you enjoy it.
First let’s take a look at the heart!
Heart is actually a muscle which pumps blood throughout our body 24/7. it has 3 main
parts, The Arteries, The Veins, The Capillaries. The wall of the heart has 3 separated
layers,
, *The Arteries are the one who actually carry the oxygen-rich blood to the body organs,
**The Veins help the body remove low-oxygen blood and waste by taking them to
Lungs.
***The Capillaries are the one who branch out of the heart, from the main vessels,
and are kinda responsible for completing the circulatory system by connecting arteries
to veins!!
