The endocrine system consists of a group of glands and organs that regulate and control various body functions by producing and secreting hormones. Hormones are chemical substances that affect the activity of another part of the body.

Endocrine Function

Human endocrine system , group of ductless glands that regulate body processes by secreting chemical substances called hormones. Hormones act on nearby tissues or are carried in the bloodstream to act on specific target organs and distant tissues. Diseases of the endocrine system can result from the oversecretion or undersecretion of hormones or from the inability of target organs or tissues to respond to hormones effectively. It is important to distinguish between an endocrine gland, which discharges hormones into the bloodstream, and an exocrine gland , which secretes substances through a duct opening in a gland onto an external or internal body surface. Salivary glands and sweat glands are examples of exocrine glands.

Internal Regulators: The Endocrine Glands Stimulate and Control Body Functions

The glands of the endocrine system secrete hormones into the bloodstream to maintain homeostasis and regulate metabolism. The hypothalamus and the pituitary gland are the command and control centers, directing hormones to other glands and throughout the body. Other primary endocrine glands, including the thyroid and parathyroid glands, the adrenal glands, and the pineal gland, adjust the levels of various substances in the blood and regulate metabolism, growth, the sleep cycle, and other processes. Organs such as the pancreas also secrete hormones as part of the endocrine system. Secondary endocrine organs include the gonads, kidneys, and thymus. The hypothalamus and the pituitary gland are part of the diencephalon region of the brain.


It uses information it gets from your brain to tell other glands in your body what to do. It makes many important hormones, including growth.

Upon reaching a target site, a hormone binds to a receptor, much like a key fits into a lock.

The endocrine system is a network of glands and organs located throughout the body. However, while the nervous system uses nerve impulses and neurotransmitters for communication, the endocrine system uses chemical messengers called hormones. Keep reading to discover more about the endocrine system, what it does, and the hormones it produces. The endocrine system is responsible for regulating a range of bodily functions through the release of hormones. Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body.

Endocrine System Overview

The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things. The endocrine system is made up of the pituitary gland , thyroid gland , parathyroid glands , adrenal glands , pancreas , ovaries in females and testicles in males , according to the Mayo Clinic. The word endocrine derives from the Greek words "endo," meaning within, and "crinis," meaning to secrete, according to Health Mentor Online.
