Explain the feedback mechanism to regulate the action of the hormones with the help of one suitable example.
Feedback mechanism is the mechanism in our body to maintain the hormonal levels in the body in desirable amount. An increase or decrease in the hormonal level in our body triggers the feedback mechanism.
The body has two types of feedback mechanisms:
1 Positive feedback mechanism.
2.Negative feedback mechanism.
Example:
Negative feedback mechanism:
Whenever there is increase in hormonal levels in our body, messages are sent to decrease secretions so that hormonal level comes to normal value and the body state is restored to normal conditions.
Such a mechanism is called a negative feedback mechanism.
The increase in the 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.
