The endocrine system is made up of glands and the hormones they secrete. Although the endocrine
glands are the primary hormone producers, the brain, heart, lungs, liver, skin, thymus, gastrointestinal mucosa, and placenta also produce and release hormones.
The primary endocrine glands are the pituitary (the master gland), pineal, thyroid, parathyroid, islets of
Langerhans, adrenals, ovaries in the female and testes in the male.
The function of the endocrine system is the production and regulation of chemical substances called hormone.
A hormone is a chemical transmitter. It is released in small amounts from glands, and is transported in the bloodstream to target organs or other cells.
Hormones are chemical messengers, transferring information and instructions from one set of cells to another.
The endocrine system and nervous system work together to help maintain homeostasis… balance.
The hypothalamus is a collection of specialized cells located in the brain, and is the primary link
between the two systems. It produces chemicals that either stimulate or suppress hormone
secretions of the pituitary gland.
