Question

Quizplus · Accepted Answer

The vertebral arteries run along the spinal column and enter the skull through the foramen magnum. The two branches merge to form the basilar artery, which supplies blood to the posterior part of the brain. The internal carotid arteries supply blood to the anterior part of the brain, while the subclavian arteries supply blood to the arms and upper chest. The brachiocephalic artery is a large artery that arises from the aortic arch and splits into the right subclavian artery and the right common carotid artery.
