Which arteries predominantly supply the brain?

The brain’s main blood supply comes from the internal carotid arteries as part of the anterior circulation, which feed the major cerebral arteries and form connections with the posterior circulation through the Circle of Willis. The vertebral arteries also contribute, but the internal carotid arteries are the primary source for most of the brain’s hemispheres. The external carotid arteries supply the face and scalp, not brain tissue, while the coronary arteries feed the heart and the renal arteries feed the kidneys.
