Final answer:
The cerebral arteries supply blood to the brain, nourishing different lobes such as the frontal, temporal, and parietal lobes.
Step-by-step explanation:
The cerebral arteries supply blood to the brain. This includes arteries such as the anterior cerebral artery that supplies the frontal lobe, the middle cerebral artery that supplies the temporal and parietal lobes, and branches of the posterior cerebral artery that form part of the posterior portion of the arterial circle. The left gastric artery, a branch of the celiac trunk, specifically supplies blood to the stomach, while the lumbar arteries coming off the abdominal aorta supply the lumbar region, the abdominal wall, and the spinal cord. However, these are separate from the cerebral arteries. Therefore, the correct answer to the question 'Where do the cerebral arteries supply blood?' is C. Brain.
The cerebral arteries supply blood to the brain.
