THE MAIN FUNCTION OF THE ENDOCRINE SYSTEM

      The main function of endocrine glands is to secrete hormones directly into the bloodstream. Hormones are chemical substances that affect the activity of another part of the body. In essence hormones act as little messengers controlling and conducting activities throught the body. When a hormone has reached its target or destination it connects with a receptor like a key in a lock. Once the hormone has made a connection with the receptor the hormone channels a message that causes the destination to take a specific action or control. Hormone receptors may be within the nucleus or on the surface of the cell. Although hormones circulate throughout the body, each type of hormone influences only certain controls into the bloodstream.
           
       

       Ultimately, hormones control the function of entire organs, affecting such diverse processes as growth and development, reproduction, and sexual characteristics. Hormones even influences the way the body uses and stores energy and control the volume of fluids and the levels of salt and sugars in the bloodstream. Very small amounts of hormones can trigger very large responses in the body.
