How many coronary arteries in the body?

There are too many to count. There are also variations from person to person. The biggest arteries branch into smaller arteries and those branch into smaller and smaller arteries down to the arterioles, which are very small and there are many of them. Some people say there are millions of arteries in the human body. One source says there are so many arteries in the body that if you laid them end to end, they would be about 60,000 miles long.


What are the arteries and its functions?

In the body arteries are tubes that carry the blood from the heart out to the rest of the body, where nutrients are picked up by the cells. After all the nutrients are gone from the blood, veins are the tubes that carry the blood back to the lungs, where it gets more oxygen, and then on to the heart, where it gets pumped out again through the arteries. In geography, arteries are main highways that carry traffic to and from major population points, or main streets that carry people from one end of the city to the other.

What is the main function of the blood vessels in the heart?

The function of the coronary arteries is to transport oxygenated blood to the heart--------not to other parts of the body !!The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries.The coronary arteries that run on the surface of the heart are called epicardial coronary arteries. These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of theheart muscle.The coronary arteries are classified as "end circulation", since they represent the only source of blood supply to the myocardium.


What is the difference between an anatomic end artery and a functional end artery?

anatomic end arteries are vessels whose terminal branches donot anastomose with branches of arteries supplying adjacent areas . Functional end arteries are vessels whose terminal branches do anastomose with those of adjacent arteries , but the caliber of anastomoses is insufficient to keep the tissue alive should one of the arteries become occluded .
