Verified step by step guidance

Understand the basic function of veins in the circulatory system. Veins are responsible for carrying blood back to the heart, not away from it. This is a key point in identifying the false statement.

Review the function of the pulmonary artery. It is unique because it carries deoxygenated blood from the heart to the lungs, which is contrary to the typical function of arteries that usually carry oxygenated blood.

Examine the role of capillaries in the circulatory system. Capillaries are small blood vessels where nutrient and gas exchange occurs between blood and tissues, which is a true statement.

Consider the function of the aorta. The aorta is the main artery that carries oxygenated blood from the heart to the rest of the body, which is a true statement.

Identify the false statement by comparing each option to the known functions of the circulatory system components. The statement 'Veins carry blood away from the heart to the rest of the body' is false because veins carry blood towards the heart.
