Question

The respiratory epithelium of the conducting airways consists of

moist cuboidal epithelium.
surfactant cells.
pseudostratified ciliated columnar epithelium.
simple squamous epithelium.
ciliated squamous epithelium.

Answer 1

The respiratory epithelium of the conducting airways consists of pseudostratified ciliated columnar epithelium. Goblet cells and cilia are also present in this type of epithelium, which helps in moving mucus and trapped particles out of the respiratory tract. So, the third option is the correct answer.

Step-by-step explanation:

The respiratory epithelium of the conducting airways is composed of pseudostratified ciliated columnar epithelium. This means that it consists of a single layer of cells that appear stratified due to the arrangement of nuclei at different levels. Goblet cells, which secrete mucus, are also present in this epithelium. The cilia on the surface of the cells help to move the mucus and trapped particles out of the respiratory tract.

So, the third option is the correct answer.
