Arterowns
Arterowns, also known as arteriole, are small blood vessels that connect arteries to capillaries. They play a crucial role in the circulatory system by regulating blood flow and pressure. Arterowns have a muscular wall that allows them to constrict or dilate, which helps control the distribution of blood to different parts of the body. This regulation is essential for maintaining homeostasis and responding to changes in metabolic demands. Arterowns are found in various organs and tissues, including the skin, muscles, and internal organs. They are typically smaller in diameter than arteries and larger than capillaries, with diameters ranging from 50 to 500 micrometers. The walls of arterowns are composed of smooth muscle cells, elastic fibers, and collagen, which provide the necessary flexibility and strength for their function. Arterowns are vital for delivering oxygen and nutrients to tissues and removing waste products, thereby supporting overall physiological functions.
