The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.

Can you get a blood clot from a blown vein?

Inflammation in superficial or surface veins, such as those used to insert IV lines in the arm or to draw blood, can produce pain, redness, swelling, warmth, and discomfort. Blood clots that form in superficial veins rarely break loose and travel in the blood to cause blockage (in places such as the lungs).
