The endocrine system is the system of glands that produces endocrine secretions that help to control bodily metabolic activity and regulate body activity. The way
the endocrine system works is through an elaborate structure of glands, each
secreting hormones. Endocrine glands work similar to nerves in that they rely on various signals to operate, releasing the hormones depending on external and internal information. The endocrine system controls many bodily functions, including: reproduction, sexual development, growth and maintenance, metabolism, and responding to external stimuli. For every function it controls, the endocrine system follows this general pattern; a signal is received,hormonal response takes place, and a reaction occurs.
Hormones are like messengers in your body that give orders to your cells to do particular things. The chemical substances produced within a body, which act as "chemical messengers" as means of communication among various parts of the organism.

- Exocrine: gland that scretes a substance out through a duct, including silvary glands and sweat glands.
- Endocrine: ductless glands/ gland that selects a substance(a hormone) into the bloodstream.
- Pituitary Gland: small gland located near the brain, size of a pea, weighing 5 oz. Produces several important hormones(mutation)
- Pineal Gland: small gland in vertebrate brain that produces several important hormones(mutation)
- Ovaries: Ovum-producing reproductive organs. Foudn in both men and women.
- Steroid hormones: steroids that act as a hormone and can be divided into 5 different groups.
- Nonsteroid hormones: an organic compound that dies not contain steroids.
- Prostaglandis: any group of cyclic fatty acids with hormone like effects, notably the promotion of urine contractions.
- Homeostasis: tendency of a system, especially in the physiological system of higher animals to maintain internal stability.
- Feedback mechanism: process in which the level of one substance influences the level of another substance.
- Role of the Hypothalamus: controls temperature regulation, emotion, sexual behavior, and motivation.
- Role of the Pituitary Gland: small endocrine gland organ that controls a multitude of important functions in the body.
- Feedback Mechanism: describes the situation when output from an event of phenomenon in the past will influence.
