Heart is the most crucial organ of the human body. It fuctions from birth to the death of a person. Its main function is to pump blood. Heart muscles requires a constant supply of oxygen rich blood to nurish it. The arteries provides the heart with critical blood supply. Those arteries become narrow and restrict the flow of oxygenated blood.
Compounds of calcium, fatty matter and protiens gets deposited inside the arteries that compound is called plaque and that plaque is hard from the outside and soft from the inside which when that plaque cracks the blood clots around it resulting into starvation of oxygenated blood to the heart. Then this clotting of blood causes heart attack and a permanent damage.
