Detailed explanation-1: -Negative feedback helps to maintain homeostasis by keeping hormone levels within a narrow range. In a negative feedback mechanism, high levels of a hormone turn off further release of that hormone.
Detailed explanation-2: -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.
Detailed explanation-3: -An important example of a negative feedback loop is seen in control of thyroid hormone secretion. The thyroid hormones thyroxine and triiodothyronine ("T4 and T3") are synthesized and secreted by thyroid glands and affect metabolism throughout the body.
Detailed explanation-4: -The Endocrine system maintains homeostasis by producing hormones. These hormones are sent to different glands and organs which in turn make changes that help the body remain in balance. For example, the thyroid gland is an endocrine gland that helps to control metabolism.
