Bronchiole
In addition to the loss of cartilage and mixed glands in bronchioles, the height of the epithelium decreases as bronchioles get smaller in diameter. Although both of the bronchioles here are lined by pseudostratified columnar epithelium, the height of this epithelium is lower than that seen in the larger bronchioles of the previous images. 1000x, 400x
Pseudostratified epithelium

In addition to the loss of cartilage and mixed glands in bronchioles, the height of the epithelium decreases as bronchioles get smaller in diameter. Although both of the bronchioles here are lined by pseudostratified columnar epithelium, the height of this epithelium is lower than that seen in the larger bronchioles of the previous images. The red arrow indicates the lamina propria of a smaller bronchiole. 1000x, 400x
