The endocrine system includes all of the glands of the body and the hormones produced by those glands. The glands are controlled directly by stimulation from the nervous system as well as by chemical receptors in the blood and hormones produced by other glands. By regulating the functions of organs in the body, these glands help to maintain the bodyâs homeostasis.
Endocrine: Each hormone is a chemical that control function of many different organs. Brain hormones send orders to organs to work. Brain secretes TSH to order thyroid to work to control whole body. Sexual hormones control brain and whole body, as does Insulin controls use of sugar in whole body (brain included).
