Which blood vessels deliver oxygenated blood to the brain?

Oxygenated blood gets to the brain mainly through the internal carotid arteries. These vessels rise from the common carotids and enter the skull, branching to form the major cerebral arteries that supply the anterior and middle portions of the brain. They work alongside the vertebral arteries (which feed the posterior regions) to create the brain’s arterial network, but the internal carotids are the primary source driving cerebral blood flow. The external carotid arteries stay outside the cranial cavity and serve face and scalp tissues, not brain tissue, while the jugular veins carry blood away from the brain rather than delivering it.
