The Endocrine System
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. The hormones then tell these organs and tissues what to do or how to function.
Numerous glands throughout the body produce hormones. The hypothalamus produces several releasing and inhibiting hormones that act on the pituitary gland, stimulating the release of pituitary hormones. Of the pituitary hormones, several act on other glands located in various regions of the body, whereas other pituitary hormones directly affect their target organs. Other hormone-producing glands throughout the body include the adrenal glands, which primarily produce cortisol; the gonads i. Many of these hormones are part of regulatory hormonal cascades involving a hypothalamic hormone, one or more pituitary hormones, and one or more target gland hormones. For the body to function properly, its various parts and organs must communicate with each other to ensure that a constant internal environment i. For example, neither the body temperature nor the levels of salts and minerals i.
The main function of endocrine glands is to secrete hormones directly into the bloodstream. Hormones are chemical substances that affect the activity of another part of the body target site. In essence, hormones serve as messengers, controlling and coordinating activities throughout the body. See also Endocrine Glands. Upon reaching a target site, a hormone binds to a receptor, much like a key fits into a lock. Once the hormone locks into its receptor, it transmits a message that causes the target site to take a specific action.
Hormone , organic substance secreted by plants and animals that functions in the regulation of physiological activities and in maintaining homeostasis. Hormones carry out their functions by evoking responses from specific organs or tissues that are adapted to react to minute quantities of them. The classical view of hormones is that they are transmitted to their targets in the bloodstream after discharge from the glands that secrete them. This mode of discharge directly into the bloodstream is called endocrine secretion. The meaning of the term hormone has been extended beyond the original definition of a blood -borne secretion, however, to include similar regulatory substances that are distributed by diffusion across cell membranes instead of by a blood system. Hormonal regulation is closely related to that exerted by the nervous system , and the two processes have generally been distinguished by the rate at which each causes effects, the duration of these effects, and their extent; i.

Endocrine System Overview
Donate now on our JustGiving page. Hormones are chemicals which circulate in the blood stream and spread around the body to carry messages or signals to different parts of the body. The name hormone comes from the Greek word hormao meaning "I excite" and refers to the fact that each hormone excites or stimulates a particular part of the body known as the target gland.
Hormones are secreted in the body by several glands that are essential for the growth, development, reproduction, etc. They are secreted by special tissues in our body through endocrine glands. Different hormones have different effects on the shape of the body. Some of these hormones work quickly to start or stop a process and some will continually work over a long period of time to perform their functions.
Error: This is required. Error: Not a valid value. The hormonal system called the endocrine system in medical terminology has various glands that release different hormones. They take messages from one part of the body the gland to tell another part of the body the target cell to do something important.
