A&P 1 101 ACTUAL EXAM QUESTIONS AND
VERIFIED ANSWERS EXAM PREP
◉ How many lobes does the right lung have? Answer: 3 (superior,
middle, inferior)
◉ Air (and not food) pass in which of the following areas? Answer:
nasopharynx
◉ In the respiratory system, gas exchange occurs in the: Answer:
Respiratory bronchioles and pulmonary alveoli
◉ What happens to the epiglottis during swallowing? Answer: It
moves to cover the trachea to prevent food and liquid from entering
into the lungs.
◉ Differences of type 1 and type 2 alveolar cells? Answer: Type 1
make up 95% of alveolar epithelial cells. Type 2 makes up 5%.
Type 1 forms very thin simple squamous epithelium. Type 2 can
divide to replace damaged type 1 cells.
◉ T or F: negative pressure is used to move air into the lungs Answer:
True
, ◉ T or F: during inhalation, the diaphragm contracts to pull the lungs
open: Answer: True
◉ T or F: during inhalation, the rib cage lifts in an upward motion to
open and expand the lungs Answer: True
◉ T or F: As the thoracic cavity expands and lung volume increases,
the density of the gases filling the lungs decreases Answer: True -
think dilution
◉ T or F: when the diaphragm rises, thoracic pressure increases and
air naturally flows out of the lungs Answer: True - air naturally flows
out of the lungs because of the pressure difference
◉ Boyle's Law: Answer: Gas volume is inversely proportional to
pressure
◉ Which of the following trachea cartilages are paired? Answer:
Arytenoid
◉ Which cells are the most abundant within the alveoli? Answer:
macrophages
◉ Which is not true of bronchioles? Answer: Bronchioles can contain
simple squamous cells
