The Endocrine System

main function of Endocrine System is to releases hormones into the blood to signal other cells to behave in certain ways. It is a slow but widespread form of communication. The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body’s growth, metabolism (the physical and chemical processes of the body), and sexual development and function.
