Solved in 2 steps
- 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 5Which of the following is NOT part of the respiratory membrane or respiratory epithelium ? Diaphragm Cuboidal epithelium with cilia Stratified squamous epithelium Capillary endothelium Red blood cell Fused basement membranes between the alveolar and endothelial cellsWhat type of epithelium lines the alveoli? simple columnar simple squamous 0 0 0 0 pseudostratified stratified squamous
- 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.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.After prolonged inflammation of the mucous membrane of the nasal cavity in the patient, changes in the epithelium are observed. What epithelium has changed? Stratified columnar Stratified cuboidal Stratified squamous O Pseudostratified O Simple squamous
- 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.What kind of epithelium lines the nasal cavity, trachea and both principal bronchi? a. Stratified squamous epithelium O b. Stratified squamous epithelium in the nasal cavity and respiratory epithelium for trachea and principle bronchi O c. Pseudostratified ciliated columnar epithelium O d. Pseudostratified columnar epithelium with goblet cellsWhat type of epithelium lines the gas exchange surfaces of the alveoli? a. pseudostratified columnar epithelium b. ciliated columnar epithelium c. simple squamous epithelium d. simple cuboidal epithelium I believe that it is pseudostratified ciliated columnar epithelium but that is not an option so I don't know what one to choose.
- What kind of tissue lines most of the respiratory tract? a. Ciliated squamous epithelium b. Simple squamous epithelium c. Ciliated cuboidal epithelium d. Ciliated pseudostratified epithelium e. Stratified squamous epitheliumIn a patient with dry pleurisy, the pleural friction noise is heard. What epithelium is thus damaged? Stratified squamous Stratified columnar Pseudostratified Transitional O Simple squamousRespiratory 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
