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.
The Endocrine System

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.
List of human hormones
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.
