The endocrine system is made up of glands that produce and secrete hormones. Endocrine glandsdo not have ducts; they secrete hormones directly into the blood stream. Despite this diversity, all endocrine cells release their products, called hormones, into the extracellular space where they may act locally in a paracrine or autocrine manner and/or enter the circulatory system to act in more distant target organs. At birth, the thin rim of adult (definitive) cortex blends imperceptibly into cells of the fetal (provisional) cortex. Endocrine Wet Labs and Human Metabolism.
