Sort each description below into the correct category of either helping to warm the body up or cool the body down. Warming the Body Blood vessels constrict Muscle fibers contract - shivering occurs A layer of adipose tissue sits under the epidermis Cooling the Body Blood vessels dilate (widen) Glands produce droplets of sweat Blood is pumped faster through the body
