Final answer:
The bodily responses of sweating, increased breathing, changes in saliva production, and shivering are all mechanisms to maintain or restore homeostasis in response to changes such as temperature fluctuations and stress.
Step-by-step explanation:
The bodily responses related to changes in homeostasis mentioned in the question can be attributed to different physiological processes and stimuli:
- When the body starts to sweat, this is typically in response to an increase in body temperature. Sweating helps to cool the body down via evaporation of the sweat on the skin surface.
- An increase in breathing rate can occur due to increased physical activity, stress, or high altitudes where oxygen levels are lower, requiring the body to take in more oxygen to meet metabolic demands.
- A change in the amount of saliva produced often accompanies the ingestion of food but can also be affected by stress, which may either increase or decrease saliva production due to the autonomic nervous system's response.
- When the body starts to shiver, it is usually a reaction to a decrease in body temperature. Shivering is a reflex involving muscle contractions to generate heat and warm the body.
All these responses help to maintain or restore homeostasis in the face of internal or external changes.
