Final answer:
The nasal cavity is lined by the pseudostratified ciliated columnar epithelium, which is a single layer of cells with goblet cells that produce mucus, aiding in trapping debris and pathogens.
Step-by-step explanation:
The epithelium that lines the nasal cavity and includes goblet cells is known as the pseudostratified ciliated columnar epithelium. These epithelial cells are unique because they give the appearance of being stratified due to the different levels of nuclei; however, they are a single layer of cells, which means they are considered a simple tissue, not a stratified one. The goblet cells dispersed among them produce mucus that traps particulate matter and pathogens. Additionally, the cilia on the apical surface move mucus laden with debris out of the respiratory tract, aiding in bodily defense. The lamina propria beneath the epithelium contains seromucous glands that contribute to mucus production and provide a moist environment that helps to warm and humidify incoming air.
