Document Summary
Carry oxygenated blood from heart to brain and other areas of the body. Carry deoxygenated blood from brain and other parts of the body back to the heart. Two large internal carotid arteries are located on either side of the upper neck. Two vertebral arteries travel upwards along the cervical vertebral column and enter the cranium though the foramen magnum. The tow vertebral arteries unite at the base of the medulla to form the. The basilar artery then travels along the midline of the ventral surface of the pons. The carotid and basilar arteries are connected to form a circle of blood vessels around the base of the brain called the circle of willis. The posterior connection between carotid artery and branch of the basilar artery is made by the posterior communicating artery. The anterior connection between branches of the carotid artery on each side is made by the anterior communicating artery.
