  11. 11.  Muscle wall between the chest and the abdomen that the body uses for breathing
  12. 12.  Cellular respiration requires glucose and oxygen to release energy to the body  C6H12O6  +  6O2    6CO2  +  6 H2O  +  Energy  Oxygen is provided by the respiratory system  Glucose is provided by the digestive system  (glucose is made during photosynthesis)
