  • Aerobic and anaerobic respiration
    • Energy is needed for the following life processes:
      • Growth
      • cell division
      • muscle contraction
      • Protein synthesis
      • active transport
      • nerve impulses
    • respiration involves chemical reactions that break down nutrient molecules in living cells to release energy
    • Aerobic respiration requires oxygen
    • glucose + oxygen ---> carbon dioxide + water
    • Anaerobic respiration happens in muscles during hard exercise
      • Glucose is not completely broken down, so much less energy is released than during aerobic respiration
      • Untitled
    • glucose ---> lactic acid
    • structures found in the human thorax
      • Trachea
      • bronchi
      • alveoli
      • Ribs
      • intercostal muscles
      • pleural membranes
      • diaphragm
    • Inhale and exhale
    • Gas exchange in the lungs
      • thin walls (just one cell thick)
      • large surface area
      • moist surface
      • many blood capillaries
