# data[].attributes.body
Blood vessels constrict so that heat is conserved. Sweat glands do not secrete fluid. Shivering (involuntary contraction of muscles) generates heat which warms the body.

Blood vessels dilate resulting in heat loss to the environment.  Sweat glands secrete fluid. As the fluid evaporates, sweat and heat is lost from the body.
