The term hormone was introduced by Bayliss and Starling in 1902 to describe a chemical substance that travels around the body influencing physiology and behavior (Gibson, 2010). Hormones tell the body to execute certain physical and intellectual behaviors’. The system that is responsible for producing hormones is called, “The endocrine system”.
