Pathophysiology Chapter 35 Structure and Function of the Pulmonary System
1. What pulmonary defense mechanism propels a mucous blanket that entraps particles
moving toward the oropharynx?
a. Nasal turbinates
b. Alveolar macrophages
c. Cilia
d. Irritant receptors on the nares
2. Which term is used to identify the movement of gas and air into and out of the
lungs?
a. Perfusion
b. Ventilation
c. Respiration
d. Diffusion
3. When an individual aspirates food particles, where would the healthcare
professional expect to hear decreased or absent breath sounds?
a. Left lung
b. Right lung
c. Trachea
d. Carina
4. Air passage among alveoli is collateral and evenly distributed because of the
function of which structures?
a. Type I alveolar cells
b. Pores of Kohn
c. Acinus pores
