An interaction of systems allows for the body to warm itself when it is cold. Which processes help the body warm up when it is cold? Check all that apply.

• shivering

• sweating

• hair on body laying flat

After the body has begun shivering, what explains why it would stop shivering?

• When body temperature returns to normal, the respiratory system sends a message to the skeletal system to stop shaking.

• When body temperature returns to normal, the nervous system sends a message to the muscular system to stop shaking.

• While body temperature is below normal, the nervous system sends a message to the skeletal system to stop shaking.

• While body temperature is below normal, the respiratory system sends a message to the muscular system to stop shaking.

Which is an example of how the body maintains homeostasis?

• by increasing thirst when cells are low on water

• by decreasing thirst when cells are low on water

• by shivering when it is hot

• by sweating when it is cold
