Document Summary
Arrange respiratory anatomy from air entry to location of gas exchange. Ventilation: bronchial tree = bronchus, bronchioles, terminal bronchioles, distal respiratory unit defined by presence of alveoli airway components available for ge. Total lung capacity everything (all the air in one"s lungs) Forced vital capacity maximal air that you can inspire/exhale (irv, tv, erv) Measure volume of gas (l) moved in a period of time (s: l/s. Expiratory exhale flow rates measure exhaled gas volumes divided by time required to. Reflect ease w/ which you can ventilate your lungs. Related to the elasticity of the lung parenchyma: parenchyma alveoli, interstitium b/w alveolar wall, bronchi, blood vessels, lymphatic vessels, lymph nodes. Reflects status of larger airways: the forced expiratory volume" in 1 second, in healthy individuals: ~ 80% of total fvc (forced vital capacity) Reflects status of smaller, more fragile airways: the forced expiratory flow. " rate in the middle of the forced expiratory flow volume curve.
