Capillaries are the smallest blood vessels. They connect arteries and veins.
Arteries divide into smaller vessels called Arteriols. Arteriols subdivide into even smaller vessels called capillaries, where oxygen, nutrients, hormones are delivered to the tissues of the body. Waste products are also picked up by capillaries and delivered to venules which grow into larger vessels called veins. Veins deliver deoxygenated blood back to the heart.
Capillaries
The three types of blood vessels in the body are veins, arteries, and capillaries. Arteries carry blood away from the heart. Veins carry blood to the heart. Capillaries are microscopic vessels that are found in the lungs and muscles.
