this is what i know

Explanation:

Blood vessels have the ability to dilate and constrict to control body temperatre. When body temperature is too low, the tiny blood vessels near the surface of the skin (capillaries) constrict (vasoconscriction). This decreases the blood flow near the surface of the skin so less heat is lost through radiation.
