respiration

• Trachea


  The windpipe that connects the nose and mouth to the lungs
• Bronchi


  The two branches that come off the trachea and enter the lungs
• Bronchioles


  The smallest branches of the respiratory tree that lead to the alveoli
• Alveoli


  Tiny air sacs located at the end of the bronchioles where gas exchange occurs
• Number of bronchi


  There are two bronchi, one for each lung
• Where does gas exchange happen in the lungs?

  the alveoli
• The gas that enters the blood stream from the lungs is oxygen
• Equation for aerobic respiration


  Glucose + Oxygen -> Carbon dioxide + Water + Energy
• Equation for anaerobic respiration in animals

  Glucose -> Lactic acid + Energy
• Equation for anaerobic respiration in fermentation


  Glucose -> Ethanol + Carbon dioxide
• MRS GREN

  Movement, Respiration, Sensitivity, Growth, Reproductio, Excretion, Nutrition
• MRS GREN refers to the characteristics of living things
