The different types of blood vessels in the human body include arteries, veins, capillaries, lymphatic vessels, and arteriovenous malformations. Arteries carry blood away from the heart to the rest of the body, while veins return blood back to the heart. Capillaries are small blood vessels that connect arteries and veins. Lymphatic vessels transport lymph, a fluid that contains waste products, away from the tissues. Arteriovenous malformations are abnormal connections between arteries and veins.
