Answer:
Shivering, sweating, and changes in blood flow to the skin are all controlled by the autonomic nervous system.
Step-by-step explanation:
Autonomic nervous system is a part of the peripheral nervous system that regulates involuntary processes such as heart rate, breathing, and digestion.
- Shivering - It is the rapid contraction of muscles and it is controlled by the hypothalamus in the brain.
- Sweating - It is controlled by the sympathetic nervous system, which is a part of the autonomic nervous system.
- Changes in blood flow to the skin - It is also controlled by the autonomic nervous system. When the body's temperature rises, the sympathetic nervous system signals blood vessels in the skin to dilate, or widen.
