What is the anatomical name for the voice box?
A. Pharynx
Pharynx: The pharynx is the throat region (shared airway/digestive pathway), not the voice box
B. Oral cavity
Oral cavity: The oral cavity is the mouth, not the voice box
C. Larynx
Larynx: The larynx is the anatomical name for the voice box
D. Trachea
Trachea: The trachea is the windpipe below the larynx, not the voice box

Which statement describes the trachea?
A. It is lined with simple squamous epithelium.
It is lined with simple squamous epithelium: The trachea is lined with pseudostratified ciliated columnar epithelium, not simple squamous
B. It contains no air-filtering mechanisms.
It contains no air-filtering mechanisms: the trachea has mucus and ciliated cells that trap and move particles (air-filtering mechanisms present)
C. It is comprised of C-shaped cartilage rings.
It is comprised of C-shaped cartilage rings: The trachea is supported anteriorly by C-shaped hyaline cartilage rings that keep the airway open
D. It is a passageway for food and for air.
It is a passageway for food and for air: The trachea is only an air passageway; the esophagus transports food

What changes occur as the respiratory tract branches into smaller and smaller tubes?
A. Their epithelial lining changes to connective tissue.
Their epithelial lining changes to connective tissue. -The lining transitions from pseudostratified ciliated columnar to cuboidal to simple squamous, but never connective tissue.
B. Their epithelial lining becomes thinner.
Their epithelial lining becomes thinner. -This thinning allows efficient gas exchange at the alveolar level.
C. They have relatively thicker epithelial lining.
They have relatively thicker epithelial lining. -The epithelium actually becomes progressively thinner.
D. They have relatively more cartilage.
They have relatively more cartilage. -Cartilage decreases as bronchi branch into bronchioles, disappearing entirely in terminal bronchioles.

The presence of which of the following, in the alveoli ensure that particles brought in with inhaled air are removed?
A. macrophages
Macrophages -Alveolar macrophages (dust cells) engulf debris, dust, and pathogens.
B. surfactant
Surfactant -Surfactant reduces surface tension, preventing alveolar collapse, but does not remove particles.
C. antibodies
Antibodies -Antibodies neutralize pathogens but do not actively remove inhaled particles.
D. lymphocytes
Lymphocytes -Lymphocytes mediate immune responses but are not the main mechanism for clearing inhaled debris.
