It is winter. You are very cold. Your body systems cooperate and respond to the cold in three ways in an effort to keep you warm. Choose the answer that is NOT correct. Your nervous system slows down and the impulses that move your muscles also slows, helping to retain heat.

The body will try to generate heat itself by allowing muscles and organs to shake within the body: this is known as shivering.

Blood flow is diverted from muscle tissue to fat. The rapid decomposition fat (adipose) tissue generates heat energy that helps to raise the body's temperature.

Cold causes blood vessels to constrict and blood flow resistance to increase. Reducing blood flow to the skin and the extremities reduces heat transferred to the environment.
