Verified Q&A Resource
This chapter test bank covers key concepts, multiple-choice questions, and critical thinking practice
related to fetal lung development. Verified content areas include:
Key Learning Objectives
Identify stages of fetal lung development.
Understand the embryonic, pseudoglandular, canalicular, saccular, and alveolar phases.

MULTIPLE CHOICE
1. Which of the following phases of human lung development is characterized by the formation
of a capillary network around airway passages?
a. Pseudoglandular
b. Saccular
c. Alveolar
d. Canalicular
ANS: D
,The canalicular phase follows the pseudoglandular phase, lasting from approximately 17
weeks to 26 weeks of gestation. This phase is so named because of the appearance of vascular
channels, or capillaries, which begin to grow by forming a capillary network around the air
passages. During the pseudoglandular stage, which begins at day 52 and extends to week 16
of gestation, the airway system subdivides extensively and the conducting airway system
develops, ending with the terminal bronchioles. The saccular stage of development, which
takes place from weeks 29 to 36 of gestation, is characterized by the development of sacs that
later become alveoli. During the saccular phase, a tremendous increase in the potential gas-
exchanging surface area occurs. The distinction between the saccular stage and the alveolar
stage is arbitrary. The alveolar stage stretches from 39 weeks of gestation to term. This stage
is represented by the establishment of alveoli.
REF: pp. 3-5
, 2. Regarding postnatal lung growth, by approximately what age do most of the alveoli that will
be present in the lungs for life develop?
a. 6 months
b. 1 year
c. 1.5 years
d. 2 years
ANS: C
Most of the postnatal formation of alveoli in the infant occurs over the first 1.5 years of life.
At 2 years of age, the number of alveoli varies substantially among individuals. After 2 years
of age, males have more alveoli than do females. After alveolar multiplication ends, the
alveoli continue to increase in size until thoracic growth is completed.
REF: p. 6
3. The respiratory therapist is evaluating a newborn with mild respiratory distress due to tracheal
stenosis. During which period of lung development did this problem develop?
a. Embryonal
b. Saccular
c. Canalicular
d. Alveolar
ANS: A
The initial structures of the pulmonary tree develop during the embryonal stage. Errors in
development during this time may result in laryngeal, tracheal, or esophageal atresia or
stenosis. Pulmonary hypoplasia, an incomplete development of the lungs characterized by an
abnormally low number and/or size of bronchopulmonary segments and/or alveoli, can
develop during the pseudoglandular phase. If the fetus is born during the canalicular phase
(i.e., prematurely), severe respiratory distress can be expected because the inadequately
developed airways, along with insufficient and immature surfactant production by alveolar
type II cells, gives rise to the constellation of problems known as infant respiratory distress
syndrome.
