Can you give me some facts about the ENDOCRINE system ?
1) In physiology, the endocrine system is a system of glands, each of which secretes a type of hormone directly into the bloodstream to regulate the body.2) The endocrine system is in contrast to the exocrine system, which secretes its chemicals using ducts.3) Features of endocrine glands are, in general, their ductless nature, their vascularity, and usually the presence of intracellular vacuoles or granules storing their hormones.4) The endocrine system's effects are slow to initiate, and prolonged in their response, lasting for hours to weeks.
