Explanation:

• Arteries carry blood away from the heart, are the largest blood vessels in diameter, and have a thick endothelial layer to withstand high pressure.
• Veins carry blood back to the heart, as they transport deoxygenated (or oxygenated in the case of pulmonary veins) blood toward the heart.
• Capillaries are single-walled vessels, which allows them to exchange nutrients and gases with surrounding tissues.
