Detailed explanation-1: -Body temperature control is a negative feedback system that occurs in the body. If the body temperature rises or falls, the response of shivering or sweating will reverse the change that has occurred.
Detailed explanation-2: -Shivering in response to a cold environment is an example of negative feedback because shivering is an adverse change in response to a cold environment. Shivering brings body temperature to an optimal state by contraction of muscles.
Detailed explanation-3: -Another example of negative feedback is the regulation of the blood calcium level. The parathyroid glands secrete parathyroid hormone, which regulates the level of calcium in the blood. If calcium decreases, the parathyroid glands sense the decrease and secrete more parathyroid hormone.
Detailed explanation-4: -Sweating is a good example of negative feedback.
Detailed explanation-5: -Negative feedback-example If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level. Once the body temperature is back to the correct level, sweating will stop.
