Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The main endocrine glands include the pituitary gland, pancreas, ovaries, testes, thyroid gland, and adrenal glands. The hypothalamus is a neuroendocrine organ. Other organs which are not so well known for their endocrine activity include the stomach, which produces such hormones as ghrelin.

Are hormones secreted in large or small amounts Are they secreted constantly or only based on the bodies demands Are their responses longer and faster or shorter and slower than the nervous system?

Hormones have a wide variety of actions, over a range of concentrations and of varying periods of time. Typically hormones provide a slower response to a stimulus than a nervous response. many hormones require a trigger that has a nervous response. most hormones act over a longer time period, these time periods are not measured in milliseconds as are nervous responses. Hormones are released when required, this means that they can be secreted over prolonged periods of time - for example the growth hormones and sex hormones. or only when needed such as the case for insulin or adrenalin (epinephrine).
