There are five types of blood vessels: the arteries, which carry the blood away from the heart; the arterioles; the capillaries, where the exchange of water and chemicals between the blood and the tissues occurs; the venules; and the veins, which carry blood from the capillaries back towards the heart.
The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries. Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances.

Aug 8, 2023 · Aside from capillaries, blood vessels are all made of three layers: The adventitia or outer layer which provides structural support and shape to the vessel. The tunica media or a middle layer composed of elastic and muscular tissue which regulates the internal diameter of the vessel.
Describe the basic structure of a capillary bed, from the supplying metarteriole to the venule into which it drains. Compare and contrast veins, venules, and venous sinuses on the basis of structure, location, and function. Discuss several factors affecting blood flow in the venous system.
The vessels of the blood circulatory system are: Arteries. These are blood vessels that carry oxygenated blood away from the heart to the body. Veins. These are blood vessels that carry blood from the body back into the heart. Capillaries. These are tiny blood vessels between arteries and veins that distribute oxygen-rich blood to the body.
