The heart is one of the vital organs of the human heart. Located on the left of the chest, the heart is about 15 cm and a weight of around 325 grams.


It consists of four main parts: the left atrium, left ventricle, right atrium and right ventricle. The heart works as a kind of natural pomp. Propelling the blood throughout the body, the heart beats are thus responsible for the bloodstream. The heart may be subject to various diseases. If it is too damaged, a heart transplant may be considered.
