Verified step by step guidance

Understand the primary function of arteries in the circulatory system. Arteries are blood vessels that carry blood away from the heart to various parts of the body.

Recognize the difference between arteries and veins. Arteries carry oxygenated blood away from the heart, except for the pulmonary arteries which carry deoxygenated blood to the lungs.

Identify the structural characteristics of arteries. Unlike veins, arteries do not have valves because the pressure from the heart is sufficient to keep blood flowing in one direction.

Clarify the role of arteries in gas exchange. Gas exchange occurs in the capillaries, not in the arteries. Arteries transport blood to the capillaries where oxygen and carbon dioxide are exchanged.

Review the statement options and determine which accurately describes the function of arteries. The correct statement is: 'Arteries carry blood away from the heart.'
