How do hormones work?

What are hormones, and what do hormones do?

Over our lifetimes, our bodies undergo a series of extraordinary metamorphoses: we grow, experience puberty, and many of us reproduce. Behind the scenes, the endocrine system works constantly to orchestrate these changes.

Hormones are messengers that are released mainly by glands, and they travel in the bloodstream through all parts of the body to targeted cells. Hormones then tell these cells what to do.
