b.the highest pressure is found in the artery because it carries the oxygenated blood and the heart pump the blood with great force thus tge artery have the highest pressure . and it also wanted to transport the oxygen quickly to other parts of the body.
c. valves. these prevent the backflow of the blood in capillary as the blood moves against the gravity.so valves prevent the blood from going back . therefore the valves help the blood in veins to move back to heart. (not sure)
