Heart & Blood Vessels: Your Coronary Arteries. 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. Left Main Coronary Artery (also called the left main trunk)
Vertebral artery. The vertebral arteries are major arteries of the neck. They arise as branches from the subclavian arteries or can arise from aortic arch and merge to form the single midline basilar artery. As the vertebrobasilar system, they supply blood to the upper spinal cord, brainstem, cerebellum, and posterior part of brain.
