What is the Endocrine System?
Endocrine systems, also referred to as hormone systems, are found in all mammals, birds, fish, and many other types of living organisms. They are made up of:. Hormones act as chemical messengers that are released into the blood stream to act on an organ in another part of the body. Although hormones reach all parts of the body, only target cells with compatible receptors are equipped to respond. Over 50 hormones have been identified in humans and other vertebrates. Hormones control or regulate many biological processes and are often produced in exceptionally low amounts within the body.

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. The endocrine glands influence reproduction, metabolism, growth and many other functions. Below is a list of the main glands see diagram for their location , some of the hormones they produce and what effects they have on the body.

Relationships between endocrine and neural regulation
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.
