Here's why:
* Hormones: The endocrine system is responsible for producing and releasing hormones, which are chemical messengers that travel through the bloodstream to target cells and organs.
* Regulation: Hormones regulate a wide range of bodily functions, including growth, metabolism, mood, reproduction, and stress response.
* Glands: The endocrine system consists of various glands, such as the pituitary gland, thyroid gland, pancreas, and adrenal glands, each producing specific hormones.
While other body systems also involve chemicals, the endocrine system is specifically defined by the production and release of hormones for long-distance communication within the body.
