What happens when arteries contract?

What happens when arteries contract?

The constriction of arterioles increases resistance, which causes a decrease in blood flow to downstream capillaries and a larger decrease in blood pressure. Dilation of arterioles causes a decrease in resistance, increasing blood flow to downstream capillaries, and a smaller decrease in blood pressure.

Which blood vessels carry blood away from the heart?

The blood vessels that carry blood away from the heart are called arteries. The ones that carry blood back to the heart are called veins.

Why blood pressure is higher in arteries than veins?

Blood pressure in the arteries is much higher than in the veins, in part due to receiving blood from the heart after contraction, but also due to their contractile capacity. The tunica media of arteries is thickened compared to veins, with smoother muscle fibers and elastic tissue.
