10.18 Lung

Version française

Section of the lung of a dog.

This field shows a respiratory bronchiole (B) continuous with two alveolar ducts (*).

Along the wall of the alveolar ducts, cut longitudinally, is a series of knoblike transverse sections of fascicles of smooth muscles (arrowheads). Here the knobs are close to each other, but this is due to the collapse of the lung tissue at the time of fixation.

The alveoli (+) surrounding the alveolar ducts have also collapsed for the same reason.
