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 smaller â¦ arteries that carry oxygen-rich blood. Arteries in the arterial blood system carry oxygenated blood. Veins in the venous blood system carry de-oxygenated blood. Both types of blood vessels operate simultaneously, continually keeping cells and tissues infused with O2 and removing CO2.
