Explanation:

Hormones are chemical proteinous substances secreted in one location and transported to another location, in order to bring about a physiological effect. Hormones are secreted by endocrine glands which collectively makes up the endocrine system. Endocrine glands include testes, ovary, pancreas, thyroid, adrenal gland etc. A hormone is usually secreted when a change needs to be effected in a target cell.

What happens is that, when a particular physiological effect is needed by a target cell e.g growth, development, homeostasis, repair etc., the particular endocrine gland secretes an hormone into the bloodstream (ductless), which carries it for absorption by the target cell where it is needed. However, the level of hormone or a report of the hormone's effect is given back to the endocrine gland via a mechanism called NEGATIVE FEEDBACK. The
