Definition: The word 'arteriole' refers to a type of blood vessel that receives blood from arteria (a small blood vessel) and distributes it throughout the body. It's also known as an artery. The term originated in Latin and means "small branch." Ate- means "into" and roce- is used for "branch."
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.
Definition: The word "arterioles" means "streaming vessels." It's a group of blood vessels that circulate blood throughout the body, much like rivers flow through a river. Here's a more detailed definition: A "arteriole" is a specialized type of blood vessel. These are narrow and round in shape, about 1-2 micrometers (0.05 inches) long, and they're found in the walls and cap of the smallest blood vessels, known as arteriovenous fistula. They transmit oxygen-rich blood from the heart to the body's tissues. A "arteria" is a more general term that describes all these vessels. Arterioles are important because they help transport nutrients and gases into and out of the bloodstream. Arterioles also play a crucial role in removing waste products, like urea and carbon dioxide, from the blood before it returns to the heart. The flow of arterial blood is vital for providing oxygen to tissues, nutrient distribution, and regulating body temperature.
