Numerous organs in the body contain individual endocrine cells or endocrine

tissues mixed with other tissues. Individual endocrine cells, such as those in the
digestive organs, are part of the diffuse neuroendocrine system (DNES). Mixed
(endocrine–exocrine) organs are the pancreas, kidneys, reproductive organs of
both sexes, and placenta. Endocrine cells and endocrine tissues are discussed
with the specific exocrine organs in their respective chapters.

There are also complete endocrine organs or glands (Fig. 19.1). These
include the hypophysis, or pituitary gland (described below), thyroid gland,
adrenal (suprarenal) glands, and parathyroid glands (described in Section 2).
