The vessels that carry blood away from the heart
(a)
Veins have (a) to prevent backflow of blood.
These have valves that prevent backflow of blood
arteries
arterioles
veins
capillaries
The blood vessel labeled "C" represents a _______________.
artery
vein
capillary
none of these are correct
The thick walls of the capillaries allow the passage of food, water, and oxygen pass from the blood vessels into the body cells.
True
False
Why is the wall of a capillary only one cell thick?
to prevent the backflow of blood
to allow the capillary to stretch and recoil
to enable the capillary to withstand high-pressure blood
to allow the capillary to exchange substances
