Systems
  1. Human
    1. Respiratory
      1. Nose
        1. Air enters the body from the nose. The fine nose hairs traps dust, dirt and germs from entering the lungs.
        2. Lungs
          1. The main function is gaseous exchange. Oxygen enters the blood and carbon dioxide leaves through the lungs
          2. Wind Pipe
            1. Air travels from the nose to the lungs through the windpipe
          3. Circulatory
            1. Heart
              1. Pumps the blood throughout the body
              2. Blood vessels
                1. Lungs
                2. Muscular
                  1. Digestive
                    1. Mouth
                      1. Breaks down food into simpler forms
                      2. Gullet
                        1. Transports food from Mouth to Stomach
                        2. Stomach
                          1. Food(now simpler form) is broken into simpler substances
                          2. Small Intestine
                            1. Food is digested and nutrients are absorbed. Digestion ends at the small intestine

                                1. Undigested food is passed out through the anus
                              3. Skeletal
