MEDICAL PHYSIOLOGY

Detailed explanation-1: -The brain receives blood from two sources: the internal carotid arteries, which arise at the point in the neck where the common carotid arteries bifurcate, and the vertebral arteries (Figure 1.20). The internal carotid arteries branch to form two major cerebral arteries, the anterior and middle cerebral arteries.

Detailed explanation-2: -The carotid arteries deliver oxygen-rich blood from the heart to both the head and brain.

Detailed explanation-3: -The carotid arteries are a pair of blood vessels located on the sides of your neck that deliver blood to your brain and head.
