Explain.<\/strong><br \/>\n<strong>Feedback Mechanism <\/strong><br \/>\nEndocrine glands do not secrete their hormones at a constant rate. The rate varies with the needs of the body. Like many other functions in body, the secretion of hormones is also regulated by feedback mechanisms.<br \/>\n<strong>Definition: <\/strong><br \/>\nFeedback mechanism means the regulation of a process by the output of the same process.<br \/>\n<strong>Types: <\/strong><br \/>\nFeedback mechanisms are of two types i.e. positive and negative feedbacks.<br \/>\n<strong>In negative feedback<\/strong>, the output of a process decreases or inhibits the process. This mechanism works to return a condition towards its normal value. For example, when the blood glucose concentration rises, pancreas secretes insulin. It decreases the blood glucose concentration. Decline in the blood glucose concentration to a normal set-point inhibits the secretion of insulin. In other words, the blood glucose concentration (output) controls the process i.e. the secretion of insulin and glucagon.<br \/>\n<strong>In positive feedback<\/strong> the changes resulting from a process increase the rate of process. For example, suckling action of an infant stimulates the production of a hormone in mother. This hormone works for the production of milk. More suckling leads to more hormones which in turn leads to more milk production.<br \/>\n<a href=\"https:\/\/murreeroad.org\/Biology10\/unit-12-coordination-and-control-long-questions\/\"><img loading=\"lazy\" class=\"alignnone size-full wp-image-1462 aligncenter\" src=\"https:\/\/murreeroad.org\/Biology10\/wp-content\/uploads\/2020\/06\/back_button.png\" alt=\"\" width=\"150\" height=\"45\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Q.13\u00a0What do you mean by feedback Mechanism?
