3. The Endocrine System I. Introduction
A. = control system composed of Endocrine Glands that make Hormones
B. Major Organ Systems & Processes Controlled:
Reproduction
Growth and development
body defences
metabolism

4. C. How Hormones work Hormones are: Move in: 3. Target organs and cells
Receptors
4. Result: DNA
5. Connection to Brain: Brain/Hypothalamus
