   III.    Hormone Flip Chart
   Create a flip chart to help you learn hormones. For each of the following glands/tissue, identify the
   hormone secreted (know name, abbreviation, and alternate name, if applicable) and the function of the
   hormone on your chart.
   Hypothalamus, pituitary, thyroid, kidney, ovary, placenta, testes, pineal, thymus, pancreas, parathyroid,
   heart, GI tract

   IV.  Hormones in the Menstrual Cycle and Pregnancy
   1. What is HCG?

   2. Is hcG secreted by a pregnant woman or her child?



   3. HCG suppresses some reactions of the immune system. What adaptive advantage does this have?



   4. How is LH secretion regulated? What effects does the changing blood levels of this hormone have?



   5. Compare the roles of LH and HCG.
