The endocrine system consists of a group of glands and organs that regulate and control various body functions by producing and secreting hormones. The glands of the endocrine system do not have ducts but rather release their hormones directly into the bloodstream. While the individual organs that comprise the endocrine system have different and often unrelated functions, they are traditionally grouped together, although this organization may not have much significance for nondoctors. Doctors who specialize in disorders of the endocrine system are known as endocrinologists. Many endocrinologists further subspecialize in the functions and disorders of specific glands.
