Recognising tissues in the gas exchange system
Cartilage
-
The cartilage in the trachea has a ‘glassy’ appearance due to its translucent protoplasm
-
It contains no nerves or blood vessels
Ciliated epithelium
-
Ciliated epithelial cells are distinctive due to their:
-
Narrow cell bodies
-
Hair-like cilia located along the apical layer
-
-
The cilia are tiny projections which greatly increase the surface area of the cell
Goblet cells
-
Goblet cells can be found scattered among the ciliated epithelium of the trachea and bronchi
-
They are distinctive in the epithelium due to their lack of cilia
-
The nucleus is found towards the basal (bottom) layer of the cell, with a large Golgi apparatus and mucus granules found towards the apical layer
