2.  Glands release products  Products (hormones) broadcast information throughout body  Slower response(than nervous system) but lasts longer

3.  Chemical messengers  Bind to specific receptors on cells target cells

4.  Release secretion through duct to surface  Examples: salivary glands, gastric glands, and sweat glands

5.  Hypothalamus  Pituitary gland Robert Pershing Wadlow  Testis/Ovaries  Pancreas  Adrenal gland

7.  Help maintain homeostasis Homeostasis: stable internal environment  Examples: body temperature, water balance, and blood sugar

8.  Bloodstream carries glucose to cells  Extra glucose stored in liver  Pancreas hormones 1.) Insulin  lowers levels of glucose in blood 2.) Glucagon  raises the levels of glucose in blood
