What happens to the blood pressure when the blood vessels get longer?
liraira [26]

Answer:

:)

Explanation:

The main artery from the heart (aorta) becomes thicker, stiffer, and less flexible. This is probably related to changes in the connective tissue of the blood vessel wall. This makes the blood pressure higher and makes the heart work harder, which may lead to thickening of the heart muscle (hypertrophy).
