Students have asked these similar questions
Identify the epithelium lining a (any) component of the respiratory zone of the respiratory tract
1. simple squamous epithelium
2. simple cuboidal (ciliated) epithelium
3. simple columnar (ciliated) epithelium
4. pseudostratified columnar (ciliated) epithelium
5. stratified squamous epithelium
Choose the following:
(A) 1, 2, and 3
(B) 1 and 2
(C) 4 and 5
(D) 2, 3, and 4
(E) 3, 4, and 5
The epithelium of the respiratory tract is mostly of the pseudostratified columnar ciliated type, but in the alveoli, the tiny sacs where oxygen and carbon dioxide are exchanged between the blood and inhaled air, the epithelium is simple squamous. Explain the functional significance of this histological difference. That is, why do the alveoli not have the same kind of epithelium as the rest of the respiratory tract? Explain your answer in 4 to 5 sentences. Indicate the reference/s of your answer.
Mucous membranes (pseudostratified ciliated columnar epithelia) line most upper respiratory tract structures. Although these membranes filter the air by trapping pathogens in mucus, they are very delicate. Pieces of food passing through the oropharynx and laryngopharynx could damage this type of epithelium. Predict which type of epithelium protects the lining of the oropharynx and laryngopharynx.
