Where does your heart receive its blood from?

Your heart's blood comes from the coronary arteries.

When we are born, the arteries are big, smooth and soft. But as we grow older, we cause damage to those once-supple arteries through fast food, stress, lack of exercise and age.

Through the decades the arteries gather fatty deposits, known collectively as plaque, along their inner walls. That causes the arteries to harden and narrow in a condition called atherosclerosis.

When it is unchecked, atherosclerosis may worsen and turn into coronary artery disease, which is known as CAD.
