Question

lo 3.6. what are the major arteries that supply blood to the brain? the brachial arteries and the radial arteries. the pulmonary arteries and the aorta. the carotid arteries and the vertebral arteries. the femoral arteries and the iliac arteries. the subclavian arteries and the renal arteries.

Explanation:

The carotid arteries (internal carotid arteries) and vertebral arteries are the major blood - supply arteries to the brain. The carotid arteries branch off the common carotid arteries (from the aortic arch) and enter the skull to supply parts of the brain. The vertebral arteries (branching from the subclavian arteries) also enter the skull and join to form the basilar artery, which along with the carotid - derived arteries, forms the circle of Willis to ensure blood supply to the brain.
The brachial and radial arteries supply the arm. The pulmonary arteries supply the lungs, and the aorta is the main systemic artery but not specifically a major direct supplier to the brain (its branches like the carotids are). The femoral and iliac arteries supply the lower body. The subclavian arteries give rise to vertebral arteries (which supply the brain) but the subclavian itself (other than the vertebral branch) and renal arteries (supply the kidneys) are not major brain - supplying arteries.

Answer:

The carotid arteries and the vertebral arteries.
