Essay
40. Explain the concept of homeostasis using the example of how we regulate our body temperature.
Answers will vary but should be similar to this. Homeostasis refers to the maintenance of a constant internal environment. In terms of temperature, our body attempts to maintain an internal temperature of 37oC. When body temperature falls below this value, we shiver. The contractions of our muscles generate heat and raises temperature back towards normal. When body temperature rises above this value, we sweat. As the sweat evaporates from our skin, it pulls heat from the body, reducing temperature back towards normal.
