Expert Answer
Feedback mechanism is the process which helps to maintain the normal state of body by controlling the hormonal secretions.
There are two kinds of feedback mechanisms:
1. Negative Feedback Mechanism:
Example: Blood sugar level
The increase in blood sugar level stimulates the secretion of insulin so that the sugar level is maintained. If the blood sugar level falls below normal, then it stimulates the secretion of glucagon. Glucagon stimulates the breakdown of glycogen to glucose, and thus, the normal sugar level is maintained.
2. Positive Feedback Mehcanism:
Example: Uterine contractions during child birth. In the normal state, the uterine muscles are relaxed. One contraction of muscles stimulates the secretion of oxytocin which further increases the contraction of uterine muscles.
