    • Diabetes Mellitus (DM)
      • Blood sugar is out of control
  • 8. Adrenal Glands
    • Two Adrenal Glands
      • Sit on top of each kidney
      • Outer Cortex and inner Medulla
    • Medulla
      • Secretes Adrenaline
        • Helps us respond to danger, stressors, caffeine, low blood sugar.. Etc.
