Ambient temperature is the term used to identify the surrounding or environmental temperature. It is the nature and tendency of all things to approach ambient temperature. If you are in a room, then the ambient temperature is the room temperature.
An arteriole is a small-diameter blood vessel in the microcirculation that extends and branches out from an artery and leads to capillaries. Arterioles have muscular walls and are the primary site of vascular resistance. The greatest change in blood pressure and velocity of blood flow occurs at the transition of arterioles to capillaries.
  Arterioles are very tiny arteries. In some areas of the body there are places where arteries and veins come together in tiny formations to swap oxygenated blood (in th â¦ e arteries) for unoxygenated blood (in the veins).rterioles are small diameter vessels that branch off of your arteries. They inevitably connect arteries to capillaries. You can find them pretty much anywhere in your body.
