The secretion of hormones is an example of a physiological feedback loop. when hormones are needed, they are secreted by glands.
when the hormones are no longer needed, the glands are signaled to stop secreting the hormones until they are needed again. thus, the basic function of a physiological feedback loop is
A feedback loop is a mechanism which is used to maintain homeostasis. Homeostasis is a process by which organisms keep internal conditions constant even there are changes in the external environment. In simple terms a feedback loop checks and balances system within the body to keep hormone levels as required. Let’s understand this with an example: When your body temperature increases, certain receptors detect the change and send a message to the hypothalamus of brain it stimulates the sweat gland to produce more sweat which gives cooling effect to the body and brings body temperature to normal.
