SECTION 1: Anatomy of the Respiratory System (Questions 1-15)
1. Which structure serves as the site of gas exchange between air and blood?
A) Bronchi
B) Trachea
C) Alveoli
D) Pharynx
The alveoli are tiny air sacs surrounded by pulmonary capillaries where oxygen and carbon
dioxide are exchanged . The bronchi and trachea are conducting airways, and the pharynx
is a shared passageway for air and food .
2. The nasopharynx is unique among pharyngeal regions because it:
A) Is shared with the digestive system
B) Serves only as an air passageway
C) Contains the vocal cords
D) Is located below the larynx
Unlike the oropharynx and laryngopharynx, which transmit both air and food, the
nasopharynx is located above the soft palate and only conveys air . It also houses the
pharyngeal tonsil and openings to the Eustachian tubes .
3. Identify the structure labeled "B" in the diagram of the pharynx (Question 1 in
exam).
A) Laryngopharynx
B) Oropharynx
C) Nasopharynx
D) Nasal Conchae
, The Nasopharynx serves only as an air passageway and is the region of the pharynx at the
back of the nose .
4. Identify the structure labeled "C" in the diagram of the pharynx.
A) Oropharynx
B) Nasopharynx
C) Laryngopharynx
D) Nasal Conchae
The Oropharynx is the area directly behind the mouth and serves as part of both the
digestive and respiratory systems .
5. Identify the structure labeled "D" in the diagram of the pharynx.
A) Nasopharynx
B) Oropharynx
C) Laryngopharynx
D) Nasal Conchae
The Laryngopharynx is the third division of the pharynx, shared by both the respiratory and
digestive systems .
6. Identify the structure labeled "M" in the diagram of the nasal cavity.
A) Nasal Conchae (Superior, Middle, Inferior)
B) Nasopharynx
C) Oropharynx
D) Laryngopharynx
The nasal conchae (superior, middle, inferior) are bony projections in the nasal cavity that
increase surface area for air conditioning .
7. Identify the highlighted area (Question 2 in exam).
A) Trachea
B) Pharynx
