- - - - the process whereby glucose is broken down in the presence of O2 with the release of large amount of energy in living cells
        
        energy released is used for
        
        growth
        
        muscle contractions
        
        digestion & absorption of food substances
        
        cell division
      - CO2 and water are released as waste products
        
        occurs all the time
      - word equation
        
        glucose + oxygen → carbon dioxide + water + large amounts of energy
    - - the breakdown of glucose in the absence of oxygen
      - releases lesser energy than aerobic respiration
      - word equation
        
        plants and yeast
        
        glucose → CO2 + ethanol
        
        glucose is only partially broken down
        
        ethanol produced still contains much energy
        
        humans
        
        glucose → lactic acid + small amounts of energy
  - - - air enters through two external nostrils that lead into two nasal passages which are lined with a moist mucous membrane
        
        dust and foreign particles are trapped by the hairs in the nostrils and mucus on the mucous membrane
        
        air is moistened and warmed
        
        air in the nasal passage enters the
        
        Pharynx
        
        From the pharynx, air passes into your larynx and then into your
        
        Trachea

        if more than half the area of the square is occupied, it will be taken as part of the reading
        
        if less than half the area is occupied, it will not be taken as part of the reading

- - - - however, there's a limit to the rate of breathing and heartbeat
        
        muscles become deprived of oxygen
        
        anaerobic respiration takes place to release extra energy
        
        sufficient to keep the muscles contracting
        
        lactic acid formed will cause fatigue and muscular pain
        
        after resting, the lactic acid will be removed from the muscles and transported to the liver, where some of the lactic acids is broken down to release energy
