A gland is a group of cells in an animal's body that synthesizes substances (such as hormones) for release into the bloodstream (endocrine gland) or into cavities inside the body or its outer surface (exocrine gland). These glands often secrete hormones which play an important role in maintaining homeostasis.
A hormone (from the Greek participle ὁρμῶν, "setting in motion") is any member of a class of signaling molecules, produced by glands in multicellular organisms, that are transported by the circulatory system to target distant organs to regulate physiology and behavior.
