Respiration

• Aerobic respiration - respiration with oxygen
• Aerobic respiration - glucose + oxygen -> carbon dioxide + water
• Way to remember aerobic respiration- AERObic (bubble with oxygen)
• Anaerobic respiration- used to meet a sudden demand for energy or when no enough oxygen is available for aerobic respiration
• Anaerobic respiration- glucose -> lactic acid + energy
• 1. Mouth
  2. trachea
  3. bronchus
  4. bronchioles
  5. alveoli
• You breathe faster and more deeply when you exercise
• People with asthma have lungs that are too sensitive to certain things (pet hair, dust, smoke)
• During an asthma attack :

  • muscles in the bronchioles contracts
  • lining of the bronchioles become swollen
  • fluids build up in the airway
• Cigarette smoke contains tar that cover the cilia (tiny hairs) in your airways
• Cilia normally move mucus out of your airways. The damaged cilia can’t do this properly.
• The mucus sticks in your airways. This makes you cough more (smokers cough)
• Response to exercise:

  • your breathing gets faster
  • your heart rate increase
  • glucose and oxygen go to your muscles via blood
