Study Notes
- The respiratory system obtains oxygen and eliminates carbon dioxide.
- It includes nasal passages, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli.
- Mechanics of breathing involve changing thoracic cavity volume and lung pressure.
- Boyle's law states that gas volume is inversely proportional to pressure.
- Obstructive diseases reduce FEV1 and can cause air trapping.
- Restrictive diseases reduce FVC and inspiratory reserve volume.
- Airway resistance depends on factors like diameter and flow type.
- Poiseuille's law shows the relationship between resistance and airway diameter.
- Asthma exacerbations increase airway resistance and cause wheezing.
- Elastic recoil helps prevent airway collapse in expiration.
