What is the main function of arteries among blood vessels?
Answer and explanation
Correct answer: To carry blood away from the heart
The defining function of an artery is to carry blood away from the heart under relatively high pressure. Arteries usually have thick, elastic and muscular walls to withstand and regulate this pressure. Most arteries carry oxygenated blood, although the pulmonary artery carries deoxygenated blood to the lungs, so direction—not oxygen content—is the rule. Veins return blood, while urine formation and digestion are unrelated; hence A is correct.
