Explanation
Answer - B - All of the choices above are part of the circulatory system except the cerebrum, which is the part of the brain that processes sensory input and directs the body’s voluntary movements. Arteries are blood vessels that carry blood away from the heart. Veins are blood vessels that carry blood back to the heart from capillary beds. Capillaries are the smallest blood vessels, and they are the only blood vessels that allow exchange of gases and nutrients between the blood and individual cells.
