What is the Endocrine System?

The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.

The body's endocrine system includes the pancreas, the thyroid, parathyroid, pineal, hypothalamus, adrenal and pituitary glands, and the ovaries and testes. It also involves many other organs which respond to, modify, or metabolize hormones.
