The endocrine system is made up of cells and glands that make hormones and release them into the blood. These hormones help to regulate reproduction, sleep, metabolism, cell growth, and development. The word endocrine is a derivative from two Greek words: “endo”, which means within or inside, and “krinis”, which is a verb for secrete. In the endocrine system, there are different glands that each excrete different hormones. All of these glands are ductless, and secrete their hormones straight into the blood stream. Some of these glands are the pineal gland, the thyroid and parathyroid glands, the pancreas, and the thymus. These glands are located in various parts of the body.

The pituitary gland is also known as the master gland, as its hormones control other glands. It produces growth hormone, which helps the body grow its tissue and bone, and also helps with taking care of the body’s nutrients, prolactin, which is a milk-producing hormone in females, thyrotropin, which sends signals to the thyroid to produce hormones, and corticotropin, which also sends signals to produce hormones, but to the adrenal gland. The hypothalamus produces anti-diuretic hormone, which raises up the water absorption in the blood in the kidneys, oxytocin, which aids in the contraction of uterine smooth muscles and contraction of mammary gland cells, or lactation. The pineal gland produces one hormone, called melatonin. This hormone is dedicated to sense light. The islet cells in the pancreas are shared by both the digestive system and endocrine system. The pancreas produces insulin, which helps the body to use and absorb glucose, and glucagon, which help the other hormone, insulin, to keep a normal blood glucose level. The kidneys are both included in the urinary system and the endocrine system. On top of the kidneys are the adrenal glands, which produce the hormones hydrocortisone and corticosterone. Hydrocortisone keeps track of how the fats, carbohydrates, and protein turn into energy for the body. Corticosterone works with the other hormone, hydrocortisone to maintain immune system responses.
