Question

question 24
which blood vessel is equipped with valves to direct blood flow?
veins
arteries
venules
capillaries

Explanation:

Veins are blood vessels that carry deoxygenated blood back to the heart. They have valves to prevent the backflow of blood. Arteries carry oxygenated blood away from the heart and do not have valves (except at the connection to the heart). Venules are small veins that collect blood from capillaries. Capillaries are the smallest blood vessels where the exchange of substances between blood and tissues occurs.

Answer:

Veins
