Scanning electron microscopy was used to examine the interparabronchial septa of chickens as a potential site of lymphatic drainage in the avian lung. Anaesthetized chickens were subjected to extracellular fluid volume expansion to produce pulmonary oedema as a result of increased capillary fluid flux into the interstitial spaces of the lung. In normal (control) chickens, the adjacent parabronchi were separated by a minimal septal space. In the "volume-loaded" birds, however, the interparabronchial septal spaces were measurably thickened and engorged as a result of hydrostatic pulmonary oedema. These results, which were consistent with reports of the effect of hydrostatic pulmonary oedema in mammals, suggest that the interparabronchial septum is a potential route of lymphatic drainage in the avian lung.
