Detailed explanation-1: -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.

Detailed explanation-2: -There is a wall (septum) between the two atria and another wall between the two ventricles. Arteries and veins go into and out of the heart. Arteries carry blood away from the heart and veins carry blood to the heart. The flow of blood through the vessels and chambers of the heart is controlled by valves.

Detailed explanation-3: -The aorta (the main artery in your body) carries the blood from the left side of your heart to the rest of your body through many branches of arteries. Capillaries have thin walls that allow oxygen, nutrients, carbon dioxide and waste products to pass through, to and from the tissue cells.

Detailed explanation-4: -Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away.

Detailed explanation-5: -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.
