Explanation:
Detailed explanation-1: -Arteries contain smooth muscle cells, which contract and relax to change the diameter of blood vessels, controlling blood flow to ensure that cells get the correct amount of oxygen and nutrients.
Detailed explanation-2: -Each time the heart beats (contracts and relaxes), pressure is created inside the arteries. When the heart is relaxed, the arteries stay at a lower resting tone to maintain some pressure in the artery.
