Chapter 5, Problem 4TYC
The epithelium of the respiratory tract is mostly of the pseudostratified columnar ciliated type, but in the alveoli–the tiny air 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 don’t the alveoli have the same kind of epithelium as the rest of the respiratory tract?

The structure in the lungs known as the respiratory membrane is where gases are exchanged -oxygen leaves the lungs and enters the blood, and carbon dioxide leaves the blood and enters the lungs. The respiratory membrane is composed of two extremly thin layers of simple squamous epithelium. Explain how the structure of the respiratory membrane follows its function.
Respiratory Histology: For each of the following parts of the respiratory tract, indicate the type of epithelium found there (simple squamous, stratified squamous, pseudostratified ciliated columnar), and why that location requires the type of epithelium that it has.
Part of the Respiratory Tract
Type of Epithelium
Vestibule of the nostril
Laryngopharynx
Nasal cavity
Nasopharynx
Oropharynx
Alveoli
The respiratory membrane is composed of two extremely thin layers of simple squamous epithelium. Explain how this structure supports or helps the function of the respiratory membrane.
