What does the endocrine system do?

Although we rarely think about the endocrine system, it influences almost every cell, organ, and function of our bodies. The endocrine system plays a role in regulating mood, growth and development, tissue function, metabolism, and sexual function and reproductive processes.

The endocrine system is made up of glands in your body. These glands send hormones into your bloodstream. Hormones are chemicals that tell cells and organs what to do. Your body makes hundreds of hormones. They help control things like your appetite and your blood pressure. They even play a role in how your body reacts to stress.
