Chapter 4, Problem 3CT
Summary Introduction
To analyze:
The increase in the mucus accumulation the lungs of a smoker when compared to normal lungs.
Introduction:
The respiratory system is responsible for the exchange of gases between the blood and the external environment. The human body uses the respiratory system to take in and absorb oxygen and expel out carbon dioxide. The respiratory system is divided into various structures that function to accomplish the gaseous exchange.

Humphrey has smoked for years. In the past few months, mucushas accumulated in his lungs and he coughs often. A tissue sample(biopsy) taken from the lower portion of his trachea indicated thatstratified squamous epithelium has replaced the normal pseudostratified columnar epithelium lining the trachea. Humphrey’s physicianexplained that he has bronchitis, inflammation of the respiratoryairways, caused by smoking. As a result, some of the normal epithelium of the large respiratory passageways has been converted tostratified squamous epithelium. Explain why mucus has accumulated in Humphrey’s lungs to a greater degree than normal.
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.
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
