MULTIPLE CHOICE AK
1. Which of the following phases of human lung development is characterized by the formationof a
AK AK AK AK AK AK AK AK AK AK AK AK AK A
K AK AK
capillary network around airway passages? AK AK AK AK
a. Pseudoglandular
b. Saccular
c. Alveolar
d. Canalicular
ANS: D A K
The canalicular phase follows the pseudoglandular phase, lasting from approximately 17 weeks
AK AK AK AK AK AK AK AK AK AK AK AK
to 26 weeks of gestation. This phase is so named because of the appearance of vascularchannels, or
AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK A
K AK
capillaries, which begin to grow by forming a capillary network around the air passages. During
AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK

minal bronchioles. The saccular stage of development, which takes place from weeks 29 to 36 of g
AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK
estation, is characterized by the development of sacs thatlater become alveoli. During the saccula

K AK AK AK AK AK
r phase, a tremendous increase in the potential
AK AK AK AK AK AK AK
gas-
exchanging surface area occurs. The distinction between the saccular stage and the alveolar s AK AK AK AK AK AK AK AK AK AK AK AK AK
tage is arbitrary. The alveolar stage stretches from 39 weeks of gestation to term.This stage is

represented by the establishment of alveoli.

2. Regarding postnatal lung growth, by approximately what age do most of the alveoli that willbe AK AK AK AK AK AK AK AK AK AK AK AK AK AK A
K AK
present in the lungs for life develop? AK AK AK AK AK AK
a. 6 months AK
b. 1 year AK
c. 1.5 years AK
d. 2 years AK
ANS: C A K
Most of the postnatal formation of alveoli in the infant occurs over the first 1.5 years of life. At 2
AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK AK
years of age, the number of alveoli varies substantially among individuals. After 2 yearsof age, m
AK AK AK AK AK AK AK AK AK AK AK AK AK A

ales have more alveoli than do females. After alveolar multiplication ends, the alveoli continue t
