Question

how does feedback mechanism regulate the hormone secretion ? explain with a suitable example

Answer 1

Hey There! ☺

Nice Question! ♥

Feedback Mechanism :

♦ Timing and amount of hormones released by various glands is regulated by a mechanism called feedback mechanism.

♦ It is build up within our body.

For instance,

It is due to this mechanism, pancreases produce more insulin when blood glucose level rises. Insulin decreases glucose level.

Similarly, when blood glucose level falls than normal, pancreases produce more glucagon to increase glucose level in blood.

Thus, feedback mechanism is vital for proper functioning of our endocrine system.

Answer 2

The feedback mechanism of hormones is the mechanism through which the balance of hormone in the blood/body is maintained. The increase or decrease in the concentration of that hormone can either stimulate the secretion of that particular hormone or inhibit the hormone secretion. This is called feedback.There can be two type of feedback. One is called Positive feedback, and other is called negative feedback. The positive feedback stimulates the secretion or production of the hormone. On the counterpart, the negative feedback inhibits the secretion of the hormone.

lance of hormone in the blood/body is maintained. The increase or decrease in the concentration of that hormone can either stimulate the secretion of that particular hormone or inhibit the hormone secretion. This is called feedback.

There can be two type of feedback. One is called Positive feedback, and other is called negative feedback. The positive feedback stimulates the secretion or production of the hormone. On the counterpart, the negative feedback inhibits the secretion of the hormone.

For Example,

When we eat carbohydrate rich food, the glucose level in the blood increase. As the Blood Glucose level rise, the pancreas will secrete Insulin. This Insulin will signal the cells to take up the blood glucose. Hence The glucose level decrease in the blood. Now, if the insulin is still present in the blood, then more and more glucose will be transported inside the cell, and there would be a scarcity of the glucose in the blood. Hence to prevent this, negative feedback is generated due to low glucose level which would inhibit the insulin secretion in the blood.
