Explanation / Answer
1) Respiratory system has 3 major components- the airway, the lungs and the muscles.
The airway further includes Nasal cavity, pharynx, trachea, bronchus, bronchioles and at last into alveoli.
2) Pathway of air into lungs - Nasal cavity - pharynx - trachea - primary bronchus - secondary bronchus - tertiary bronchus - bronchioles - alveoli.
3) There are two types of cells in alveoli (aka respiratory cells)- these are pneumocyte 1 and pneumocyte 2. Pneumocyte 1 are involved in gaseous exchange while pneumocyte 2 secrete a liquid called surfactant which helps maintain the ideal surface tension to prevent alveolar collapse.
4) Tidal volume - The amount of air we breath in and out per breath - 500 mL
Inspiratory reserve volume - The amount of air that we can take in forcefully after normal inspiration - 2500-3000 ml
Expiratory reserve volume - The amount of air one can exhale after normal expiration - 1100-1200 mL
Reserve volume - The ampunt of air that remains in lungs even after forceful expiration - 1000-1100 mL
Imspiratory capacity- The amount of air that can be forcefully inspired after a normal expiration. Includes IRV and TV.
Expiratory capacity - The amount of air that can be forcefully expired after normal inspiration. Includes ERV and TV.
Vital capacity - Volume of lung that can be breathed out after forceful inspiration. Includes TV, IRV and ERV.
Total lung capacity - Includes TV, IRV, ERV and RV.
5) According to Boyle's law, pressure and volume always run inversely proportional everywhere- therefore in lungs too. PV = constant.
