Endocrine System

endocrine system  The endocrine system is comprised of several glands The human brain contains the hypothalamus, pituitary, and pineal glands The neck includes the parathyroid Abstract Endocrine organs are richly vascularized ductless organs that produce hormones The epithelial cells of the organ secrete their hormone product

Endocrine communication involves chemical signaling via the release of hormones into the extracellular fluid From there, hormones diffuse into the bloodstream The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testicles, thyroid gland, parathyroid gland, hypothalamus

Primary endocrine organs have the only function to secrete hormones , but secondary endocrine organs are primarily meant for the other The hypothalamus and the pituitary gland are part of the diencephalon region of the brain The hypothalamus connects the nervous system to the endocrine system
