The endocrine system is a network of glands and organs that produce and release hormones, chemical messengers that regulate various bodily functions like mood, growth, metabolism, tissue function, and reproduction.
Key endocrine glands include the hypothalamus, pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries, and testes, which, along with other organs like the kidneys and stomach, work together to maintain homeostasis through a complex communication network.
