Consist of Pitituary gland, Thyroid and Parathyroid glands Adrenal glands, Thymus,
Pancreas, Pineal, Ovaries (F), Testes (M)
    Functions:
          Produce chemical molecules called hormones
          Regulate processes such as growth and reproduction
      The Cardiovascular System




Commonly known as Circulatory System, includes the heart and blood vessels
   Functions:
        Heart pumps the blood
        Vessels transport blood which carries oxygen, carbon dioxide, nutrients
          and wastes

    Functions:
         Picks up fluid leaked from blood vessels and returns it to blood

the Duct System
In Females are The Ovaries Fallopian Tubes, Uterus and Vagina
    Functions:
          Production of Offspring
