Explanation The blood vessels that are close to the heart face greater pressure, that is, blood pressure lowersas the vessels spread in the body. The pressure is highest in the aorta and elastic arteries that lie close to the heart. In arterioles, pressure decline is sharpest due to a sharp increase in peripheral resistance in arteries...
