Definition: The term "arteriole" refers to a blood vessel that carries oxygenated blood. The structure of an arteriole is relatively simple, consisting of one or more capillaries, which are tiny blood vessels surrounded by a layer of endothelial cells called intima. Oxygen-rich blood from the heart travels through these capillaries and into the arteriole walls, where it's converted to oxygenated blood. The word "arteriole" also means "stream" or "channel", referring to its role in distributing blood throughout the body. In a more complex system, an arteriole may be joined by other structures like veins and arteries to form larger vessels called capillaries that carry more oxygen-rich blood. For more detailed information on the structure and function of arterioles, you might find resources from medical texts or studies in anatomy and physiology.
