The respiratory system

  1. 1. The Respiratory System
  2. 2. Purpose of the respiratory system• To provide a constant supply of oxygen to keep your body cells functioning• To remove carbon dioxide from the body cells
  3. 3. Organs of the respiratory system• Nose / mouth • Trachea• Nasal cavity • Bronchus (bronchi) Lungs• Pharynx • Bronchioles• Epiglottis • Alveoli• Larynx • Pleura• Trachea • Diaphragm
  4. 4. Figure 10.1
  5. 5. Components of the Upper Respiratory Tract Figure 10.2
  6. 6. Upper Respiratory Tract Functions Passageway for respiration Receptors for smell Filters incoming air to filter larger foreign material Moistens and warms incoming air Resonating chambers for voice
  7. 7. Components of the Lower Respiratory Tract Figure 10.3
  8. 8. Lower Respiratory Tract Functions:  Larynx: maintains an open airway, routes food and air appropriately, assists in sound production  Trachea: transports air to and from lungs  Bronchi: branch into lungs  Lungs: transport air to alveoli for gas exchange
  9. 9. Gas Exchange Between the Blood and Alveoli Figure 10.8A
  10. 10. Respiratory Cycle Figure 10.9

  12. 12. Measurement of Lung Capacity Figure 10.10A
  13. 13. Disorders of Respiratory System Reduced air flow: asthma, emphysema, bronchitis Infections: pneumonia, tuberculosis, botulism Lung cancer Congestive heart failure Cystic fibrosis
  14. 14. Relationship to digestive system• 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)
