Final answer:
Mammals regulate body temperature through various mechanisms like shivering, sweating, and metabolic rate adjustments. Skin, liver, and hypothalamus play vital roles in maintaining homeostasis.
Explanation:
Thermoregulation in Mammals:
Mammals regulate their body temperature through:
- Shivering and sweating to generate or release heat.
- Vasodilation and vasoconstriction to control blood flow near the skin.
- Adjusting metabolic rate to produce more or less heat based on size.
Role in Homeostasis:
- Skin: Regulates heat exchange with the environment.
- Liver: Maintains blood glucose levels.
- Hypothalamus: Controls body temperature and hormone secretion.
