Which of the following descriptions regarding the larynx is CORRECT?
The most inferior cartilage in the larynx is the epiglottis.
Unlike the other cartilages of the larynx, the epiglottis consists of hyaline cartilage.
The larynx contains four unpaired cartilages.
When the vestibular folds come together, they prevent air from leaving the lungs.
Given these respiratory passageways:
1. alveoli
2. bronchi
3. bronchioles
4. respiratory bronchioles
5. terminal bronchioles
From largest to smallest, the accurate order for these passageways is:
2, 4, 5, 3, 1
2, 4, 3, 5, 1
2, 3, 5, 4, 1
2, 3, 4, 5, 1
The right lung has ___ lobes and ___ bronchopulmonary segments.
2,9
2,10
3,9
3,10
The pleura that covers the surface of the lungs is the:
Pleural Cavity
Pleural Fluid
Visceral Pleura
Parietal Pleura
The muscles of inspiration include the diaphragm and internal intercostal muscles. The statement is:
True
False
Partially true
Partially false
During expiration, decreased thoracic volume results in increased pressure inside the alveoli, therefore, air moves out of the lungs. The statement is:
True
False
Partially true
Partially false
It is the volume of air inspired or expired with each breath. At rest, quiet breathing results in a volume of about 500 milliliters (mL).
Tidal volume
Inspiratory reserve volume
Expiratory reserve volume
Residual volume
Given these divisions of the pharynx: 1. laryngopharynx 2. nasopharynx 3. oropharynx From superior to inferior, the correct sequence for the divisions of the pharynx is:
1,2,3
1,3,2
2,3,1
2,1,3
Which of the following is NOT TRUE about the paranasal sinuses?
They increase the weight of the skull.
They act as resonating chamber for voice production.
They contribute to voice production.
They protect the nasal cavity by producing mucus.
Prominent bony ridges on the lateral walls of the nasal cavity which increases the surface area of the nasal cavity are called:
the choane
the nasal septa
the hard palate
the conchae
Which of the following structures is not found in the upper respiratory tract?

Which of the following statements about pulmonary ventilation is true ?
