Detailed explanation-1: -There are three types of blood vessels: Arteries carry blood away from your heart. Veins carry blood back toward your heart. Capillaries, the smallest blood vessels, connect arteries and veins.

Detailed explanation-2: -Arteries are blood vessels that carry oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood that is low in oxygen from the body back to the heart for reoxygenation.

Detailed explanation-3: -The great vessels of the heart include your aorta, pulmonary trunk, pulmonary veins and vena cava (superior and inferior). They connect directly to your heart and play a vital role in your circulatory system.

Detailed explanation-4: -These blood vessels are with low pressure and move in an upward direction, i.e. from the cells, tissues and other organs to the heart. Compared to the arteries, veins are thin-walled. Also refer: Difference between arteries and veins. Short and tiny blood vessels, found within the tissues are called capillaries.

Veins Carry Blood Back Toward the Heart. Exchange of Gases, Nutrients, and Waste Between Blood and Tissue Occurs in the Capillaries. More items
