1-14. ENDOCRINE SYSTEM
This system includes the glands which secrete hormones into the bloodstream
(see figure 1-17). Hormones are small in quantity but powerful in effect. Carried
throughout the body by the blood, hormones influence growth, blood pressure, fluid
balance, ability to use food, and sexual characteristics.
