Detailed explanation-1: -Arteries carry blood from the heart to different organs and hence it is oxygen rich in most cases. But, the blood from the heart to the lungs is carried by the pulmonary artery which needs oxygen.

Detailed explanation-2: -With the exception of pulmonary blood vessels, arteries carry oxygenated blood and veins carry deoxygenated blood. Arteries have thick walls with muscle tissue. Veins have thinner walls and use valves to keep your blood flowing.

Detailed explanation-3: -Final answer: The correct statement that describes arteries is they have thick elastic walls without valves inside, blood flows under high pressure and carries blood away from the heart to different parts of the body.

Detailed explanation-4: -A key difference between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas veins carry the deoxygenated blood to the heart, with the exception of pulmonary arteries and veins.

Detailed explanation-5: -Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
