System
The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function.
Organism
The primary function of the kidneys is to maintain the proper balance of water and minerals (electrolytes) in the body. The kidneys play an additional important role in helping to regulate activities of the endocrine system, secreting two hormones and an enzyme that play important roles in regulating red blood cells, healthy bones and blood pressure.

Organ
The major glands of the endocrine system are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and the reproductive organs (ovaries and testes). The pancreas is also a part of this system; it has a role in hormone production as well as in digestion. These are all a part of the organisms that have the endocrine system.
Homostasis
If calcium is to high then thyroid gland secretes a hormone called calcification, then bones hold on to that calcium and kidneys don't have to hold on to much. If calcium drops too low then the parathyroid gland secrete PTH which increase the amount of secretion from bone, kidney and intestine and the blood calcium level rises.
Interaction
The endocrine system interacts with the circulatory system, the nervous system, and the digestive system.The Endocrine System works with the circulatory system because it works as the transport system for endocrine information. It works with the circulatory system to send hormones throughout the body where they can be received by various organs and cells, and are then put to use through bodily functions.The Endocrine System works with the digestive system through the pancreas, which produces the hormone insulin. When we digest carbohydrates (through the digestive system) they are then transformed into sugars. The pancreas, which is part of the endocrine system, produces the hormone insulin to regulate how fast the sugars are consequently broken down; therefore, insulin regulates the amount of sugar in the blood.The Endocrine System works with the nervous system by sending hormones to cells and thereby causing a physical reaction. These hormones provide feedback to the brain and affect neural processing, which give your body instructions on how and when to react to certain extrema. Other hormones, such as reproductive hormones, affect the development of the nervous system.
