This chapter is the partner of neural control: it explains how hormones, chemical messengers carried in the blood, keep every cell of the body in step. It walks gland by gland through the human endocrine system (hypothalamus, pituitary, pineal, thyroid, parathyroid, thymus, adrenal, pancreas, testis and ovary), then the hormones made by the heart, kidney and gut, and ends with how a hormone acts once it reaches its target cell.
