An artery usually carries pure, filtered and clean blood away from the heart, to all the parts of the body with an exception of the pulmonary artery and the umbilical cord. As the arteries move away from the heart, they divide into smaller vessels. These thinner arteries are called arterioles.
This can happen when plaque deposits in the blood vessel walls rupture and a blood clot forms. If a piece of the blood clot breaks away and gets into the bloodstream, it can block the flow of blood to the heart or brain and cause a heart attack or stroke. A blood clot in an artery is called an arterial thrombosis.A blood clot in the vein is called a venous thrombosis. blood clot is a jelly-like mass of blood tissue formed by clotting (coagulating) factors in the blood. A blood clot is a normal reaction of the body that occurs if a blood vessel is injured. This is desirable if it occurs to stop the bleeding caused by an injury.
