(Rieser) [Harry] __** Background: **__ Endocrine system is a system that mostly made up of glands and responsible for growth, development, and maintain homeostasis in the body. ** Glands ** are the group of organs that specialized in making hormone in endocrine system. The major glands of endocrine system are pituitary, thyroid, hypothalamus, parathyroid, adrenals, pineal body, pancreas ,and reproductive organs (Rieser) [Harry]. Glands in endocrine system release hormones that flow in the bloodstream, hormones attach with the receptor of a cell which changes the cell’s activities. ** Hormones ** is the chemical signal that is made by glands, it travels through the bloodstream and change the cell's activities by attaching to its receptor. Hormones help adjust the body's balance of fluids and among other key roles in all the body's systems (Minard) [Harry].

("Hypothalamus") [Harry] **Hypothalamus** is also a part of nervous system, releases hormone to impulse other glands to release hormone. Hypothalamus has a small part in nervous system that is made of nuclei and responsible for many behaviors such as sleep, hunger, thirst and sex (Cherry) [Harry]. It controls the pituitary glands in endocrine systems and responsible for sending hormone to other glands and stimulate them to release hormone (Cherry) [Harry]. **Releasing hormone** is the hormone that stimulates other glands to make hormones which was sent by the hypothalamus gland to **pituitary glands** because it's next to hypothalamus.

When the temperature suddenly changes, endocrine system controls the homeostasis in the body so the hypothalamus glands will send signal message to pituitary glands so it will send signal to thyroid glands and thyroid glands will make the body more active and release heat. When the body temperature is constant again then it will stop (Nowicki 900) [Harry]. When releasing hormones continues to be produced after the body reaches its ideal condition for homeostasis, the body will become unbalance or cause severe illness and more hormones will be released to maintain homeostasis. Feedback loops keeps the hormonal regulation balance and maintains homeostasis by keeping everything in the body healthy or the same ("E ndocrine System") [Harry].
