Objectives. The histologic characteristics of the components of conducting portion and respiratory portion of the respiratory system. How these characteristics allow each component to contribute to the overall function of the respiratory system.
INITIAL DIAGNOSTIC APPROACH. Diagnostic approach to a patient in respiratory distress should consider the patient’s signalment and history as well as the broad anatomic differential diagnoses of dyspnea (Table 1, page 54).
The respiratory system begins at the nose and ends at the distal alveoli. It is comprised of the upper and lower airways. The upper airway includes the nose, sinuses, and pharynx. The nose provides olfaction and temperature regulation in hyperthermic patients.
The evolution of the vertebrate respiratory system achieved its most efficient state in birds, with their constant volume parabronchial lungs and their highly compliant air sacs with low pressure ventilation that, enabling them to sustained flapping flight.
