Which term describes the supply of blood to the brain?

Blood supply to the brain is provided by the cerebral circulation, with the internal carotid arteries delivering a major portion of oxygenated blood to the brain’s anterior regions. They enter the skull and branch to nourish the cerebral cortex, and together with the vertebral arteries form the Circle of Willis, providing redundancy to protect brain tissue from ischemia. Thus, the term that describes this supply is the internal carotid arteries. The other options don’t describe blood flow to the brain: glandular secretions relate to secretions from glands, stimuli are signals that provoke responses, and intelligence is a cognitive ability.
