Detailed explanation-1: -Arteries carry blood away from the heart and veins carry blood back to the heart.

Detailed explanation-2: -Arteries carry blood away from your heart. Veins carry blood back toward your heart. Capillaries, the smallest blood vessels, connect arteries and veins.

Detailed explanation-3: -The veins take oxygen-poor blood back to the heart. Hence, the correct option is (b).

Detailed explanation-4: -Veins carry deoxygenated blood towards your heart and are often located close to your skin. Veins don’t have a muscular layer like arteries do, so they rely on valves to keep your blood moving. Veins start as tiny blood vessels called venules, which become full-size veins as they come closer to your heart.

Detailed explanation-5: -Arteries. Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.
