Blood vessels that contain valves and rely on skeletal muscles to move blood are called: A) arterioles
B) veins
C) capillaries
D) arteries

and why!? thanks!!

veins because they carry low pressured blood due to which there is more chance for backward flow of blood and to prevent that they contain valves.

hope it helped uh..

B. Veins

Explanation:

Veins carry blood relying on the action of the skeletal muscle as the body moves. Veins have valves so blood flows in only one direction. Valves are not present in arteries. Arterioles is small and contains valves to prevent backflow of blood but does not rely on skeletal muscles. Capillaries don’t have any valves. The correct answer would be veins.
