Fig. 2.1 shows photomicrographs of lung tissue at the same magnification. One shows healthylung tissue and the other shows lung tissue from a person with COPD.
Line AB shows the diameter of one healthy alveolus. Line CD shows the diameter of an area oflung where the alveoli have been destroyed. The real diameter of healthy alveolus is 200 µm.If line AB in the picture is 2 cm, calculate the magnification of the picture......

Oxygen diffuses from the inhaled air in the alveoli of the lungs, where its concentration is higher, into
the cytoplasm of red blood cells, where its concentration is lower. Patients diagnosed with
emphysema have damaged alveoli. This results to fewer, larger air spaces instead of many small
ones. Explain how this damage can lead to shortness of breath?
The surface area of lungs is reduced. Hence, less oxygen can diffuse into the red blood
cells.
The surface area of lungs is increased. Hence, more oxygen can diffuse into the red blood
B
cells.
The surface area of lungs is reduced. Hence, more oxygen can diffuse into the red blood
cells.
The surface area of lungs is increased. Hence, less oxygen can diffuse into the red blood
cells.
What 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.
