The endocrine system uses this system of turning hormones on and off to maintain homeostasis.
A
Hypothalamus
B
Thymus
C
Negative Feedback
D
Target Cells
Explanation: 

Detailed explanation-1: -Feedback control, both negative and positive, is a fundamental feature of biological systems. Some of these systems strive to achieve a state of equilibrium or “homeostasis". The major endocrine systems are regulated by negative feedback, a process believed to maintain hormonal levels within a relatively narrow range.

Detailed explanation-2: -What is a negative feedback mechanism? A negative feedback loop is one way that the endocrine system tries to keep homeostasis (stability) in the body. If an endocrine gland senses that there is too much of one hormone in the body, it will initiate changes to decrease production of that hormone.

Detailed explanation-3: -Feedback Control of Hormone Secretion The endocrine system is controlled by complex feedback mechanisms in which the secretion of a hormone is turned on (stimulated) or turned off (inhibited), depending on its concentration. Such feedback mechanisms help the body maintain homeostasis.

Detailed explanation-4: -Negative feedback keeps the concentration of a hormone within a relatively narrow range and maintains homeostasis. Very few endocrine hormones are regulated by positive feedback loops. Positive feedback causes the concentration of a hormone to become increasingly higher.
