Functioning of the heart is very fasinating. It is responsible for circulation of the blood through out the body. But how it does it, such a tiny organ would not have mechanical power required to pump highly viscous blood through out body. Also blood mid point stoped at body cells to exchanger nutrients and waste and pick-up speed again. How is this possible if heart of was a pump ? In this video we will see how heart does this and also that we will see that it is not a pump. #howitworks #heart #NotPump
