Endocrine system
|
|
The endocrine system is a control system of ductless glands that secrete chemical messengers 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.
Diseases of the endocrine system are common, such as diabetes mellitus and thyroid disease. The field of medicine that deals with disorders of endocrine glands is endocrinology, a branch of the wider field of internal medicine.
