The Endocrine System (The Human Body-How It Works)

Much like the nervous system, the endocrine system relays important communication signals throughout the body. The endocrine system uses chemical signals, known as hormones, which are produced and stored in special glands in the body. Different glands produce specialized hormones and release them into the bloodstream. From there, these hormones can travel directly to the tissues and organs and help regulate bodily functions. In "The Endocrine System", learn how this chemical messaging system is vital to the body's growth, metabolism, and sexual development.
