Endocrine system

The endocrine system is a system of ductless endocrine glands that secrete chemicals called hormones that circulate within the body via the bloodstream to affect distant organs. It does not include exocrine glands[?] such as salivary glands, sweat glands[?] and glands within the gastrointestinal tract.
