blood flow decreases as blood vessel diameter increases

Detailed explanation-1: -Blood flow does increase when the diameter of blood vessels increases (vasodilation) and when arterioles vasodilate. Blood flow also increases when the arterial pressure increases, which causes more blood to flow through the vessels, increasing the blood pressure.
Detailed explanation-2: -High blood pressure can damage the cells of the arteries’ inner lining. When fats from the diet enter the bloodstream, they can collect in the damaged arteries. Eventually, the artery walls become less elastic, limiting blood flow throughout the body.
Detailed explanation-3: -Answer and Explanation: The statement (c) Artery walls help to maintain pressure, even between heartbeats is TRUE about blood pressure.
Detailed explanation-4: -Some examples of aerobic exercise that can help lower blood pressure include walking, jogging, cycling, swimming or dancing.
