Your endocrine system is a set of glands and the hormones they produce that help guide and regulate the development, growth, reproduction and behavior of most living things (yes plants too!). Some hormones are also released from parts of the body that aren’t glands, like the stomach, intestines or nerve cells. These usually act closer to where they are released. The endocrine system is made up of glands, which secrete hormones, and receptor cells which detect and react to the hormones. Hormones travel throughout the body, acting as chemical messengers, and interact with cells that contain matching receptors. The hormone binds with the receptor, like a key into a lock. Some chemicals, both natural and human-made, may interfere with the hormonal system. They’re called endocrine disruptors.
