No cartilage.
Lamina propria of smooth muscle and elastic and collagenous fibres
what is the lining of the vocal cords?
Stratified squamous epithelium surrounded by respiratory epithelium
‘Pseudostratified ciliated columnar epithelium and goblet cells covering cartilage and intrinsic muscles’ is the lining of which structure?
Larynx, excluding the vocal folds
what is the name of a polygonal cell that releases surfactant from lamellar bodies within its cytoplasm?
type 2 pneumocyte
what is a clara cell?

where are clara cells found?
terminal bronchioles
what is the other name for dust cells?
alveolar macrophages
they are phagocytic cells that migrates up the bronchial tree and are eventually swallowed
what is he majority cell type lining the terminal bronchioles?
Cuboidal epithelial cell
what are the squamous epithelial cells found in the alveolar sac?
type 1 pneumocyte
what are the cells of the pulmonary capillaries which contribute to the blood-air barrier?
