The heart is the core of this system, he oversees bump blood though the body, blood provides the body whit oxygen and nutrients, while removing metabolic wastes, without it non-organ can work properly and perish in a very brief time.  The heart in humans in the middle compartment of the chest, the heart is typically the size of a fist: 12 cm in length, 8 cm in wide and 6 cm in in thickness.
Sadly the heart can have a lot of diseases, some of them are Coronary artery disease, in which  the inner walls of the arteries  narrows reducing the blood flow to the heart . Another one is Heart failure, in this one the heart can't beat out enough blood to meet the needs of the body.
