Endocrine system - An animal hormone is a chemical signal that is secreted into the extracellular fluid, circulates in the blood or hemolymph, and communicates regulatory messages within the body. ○ A hormone may reach all parts of the body, but only specific target cells have the receptors that enable a response. ○ A given hormone traveling in the bloodstream elicits specific responses— such as a change in metabolism—only from its target cells while other cells are unaffected. ...
