About Endocrine System
The endocrine system covers hormone-producing glands including the pituitary, thyroid, parathyroids, adrenals, pancreas, pineal gland, ovaries and testes. It explains hormone classes, target-cell responses, feedback control, and the functions of hormones such as insulin, thyroxine, cortisol, growth hormone and ADH, which is often confused with a kidney-produced substance.
