Control of Hormone Secretion:
A feed back mechanism is a loop in which a product feeds back to control its own production. Most hormone feedback mechanisms involves negative feedback loops. Negative feedback keeps the concentration of hormone within a narrow range.
Negative feedback occurs when a product feeds back to decrease its own production. Whereas a positive feedback occurs when a product feedback to increase its own production.
We have a feedback mechanism for controlling the precise quantity and timing of hormone secretion. For example, when we take a meal, our blood sugar level rises. The response to this stimulus is the secretion of the required amount of insulin. The insulin carries glucose to the tissues. As a result, the blood sugar level falls and insulin secretion is reduced.
