What is the function of the carotid body?

What is the main blood vessel that goes to the brain?
Carotid arteries supply blood to brain . Blood is supplied to the entire brain by 2 pairs of arteries: the internal carotid arteries and vertebral arteries. The right and left vertebral arteries come together at the base of the brain to form a single basilar artery. The basilar artery joins the blood supply of the internal carotid arteries in a ring at the base of the brain. This ring of arteries is called the circle of Willis. The circle of Willis provides a safety mechanism...if one of the arteries gets blocked, the "circle" will still provide the brain with blood.
