1. How many Lobes does the right human lung have?
3 lobes
2. A) Air and Food pass in which of the following areas : Oropharynx
B) Air (and NOT food) Pass in which of the following areas: Nasopharynx
3. Rings of cartilage line much of the respiratory tract. In which of one the
following would cartilage NOT be found? D: Alveoli
4. Label the following in the Diagram:
A) Nasal Cavity
B) Oral Cavity
C) Soft Palette
D) Epiglottis
E) Glottis
F) Trachea
G) Esophagus
5. A) Explain what happens to the soft palate during swallowing:
When swallowing, the soft palate closes to help prevent food or liquid from
entering the nasal passages.
B) What happens to the epiglottis during swallowing?
When you do the action of swallowing the epiglottis blocks the entrance to
the trachea preventing food or liquid from entering the lungs.
6. Explain the difference between type 1 and type 2 alveolar cells.
Type I forms a simple squamous epithelium injunction with capillaries. They make
up roughly 95% of the alveolar epithelial cells
Type II Type II produce and secrete pulmonary surfactant which is
needed throughout the alveolar surface to keep the alveoli open. In
addition, Type II cells can divide to replace damaged Type I cells. Make
up roughly 5% of alveolar
epithelial cells
7. T/F :
A) Negative Pressure is used to move air into the lungs ( True)
B) Positive Pressure is used to move air into the lungs ( False)
8. T/F:
A) During inhalation the diaphragm contracts to pull the lungs open ( True)
B) During Exhalation the diaphragm contracts to actively push air out of the
lungs ( False)
