It varies from 0 or 1 which is common to 2-3 or even more
The penis
some times , after angiography the doctors says,this patient have two clogged arteries or three clogged arteries.My question,total how many arteries in normal human heart.and how many clogged arteries will lead the patient to death?
Coronary arteries. The orifice of the coronary arteries are located on proximal part of the ascending aorta, and there are two orifices branching into the left and right coronary arteries.The marginal, anterior and ventricular arteries provide the cardiac muscle with oxygenated blood.The coronary arteries are the major vessels bringing blood to the heart muscle. The are the left and right coronary arteries, the left having a common trunk followed by the circumflex and anterior descending branches. Each of these give off side branches which bring blood and hence oxygen to the heart muscle. Coronary arteries fill during diastole.There is a right coronary artery and the left coronary artery. In total there are four coronary arteries.
The coronary arteries supply blood to the myocardium (heart muscle).
The coronary arteries supply oxygenated and nutrient filled blood to the heart muscle. There are two main coronary arteries: right coronary artery and left coronary artery. Other arteries diverge from these two main arteries and extend to the bottom portion of the heart.

No. The coronary arteries are not the largest arteries. The aorta is the largest artery.

The heart muscle is supplied with oxygenated blood by the coronary arteries. Along with the oxygenated blood, the arteries also supplies the heart muscle with nutrient-filled blood.
the structure of coronary artery?
You will need coronary artery bypass surgery if you suffer from coronary artery disease. The procedure works by relieve angina and by grafting arteries and veins to the coronary arteries.
The myocardium (muscle) that makes up the heart has its own blood supply called the coronary circulation. The coronary circulation comprises two main arteries; the left coronary artery and the right coronary artery. They branch off from the aorta (the biggest artery in the body!) really early on. The left coronary artery branches (into left marginal artery) to supply the left atrium and ventricle (chambers). The right coronary artery branches (into circumflex and left anterior descending) to supply the right atrium and ventricle and a bit of the left ventricle. Extra for experts: the way the coronary circulation is made up can change (just like people can be short or tall) because of genetic variability. So most people (about 70% off the top of my head) are "right dominant," because their right coronary artery branches to form the posterior interventricular artery. Some people are "left dominant" because their left coronary artery branches to form the posterior interventricular artery. So just remember Aorta --> left coronary artery --> left marginal --> right coronary artery --> circumflex + left anterior descending + the posterior interventricular artery from either left or right coronary artery Hope this helps :)
