LAB 2 Exam: Respiratory System
1. List, in order, the anatomical structures found in the respiratory pathway. You should
begin at the nose and end at the alveoli.
Nose – Pharynx – Larynx – Trachea – Right and Left Bronchi – Bronchioles –
Alveoli
2. Which if the following statements is TRUE regarding structures within the respiratory
tract?
a. The trachea contains cartilaginous rings to keep it from collapsing as air flow
through it.
b. If a patient were to aspirate, the content would likely enter the left main bronchus.
c. The bronchi are a part of the respiratory division of the respiratory tract.
d. The pharynx is part of the conducting division of the respiratory tract.
e. a and d are true.
f. b and c are true.
g. All of the above statements are true.
3. You are assessing a child admitted to the hospital with croup. They are breathing at a rate
of 32 breaths per minute. What is their Alveolar Ventilation Rate? (show your
calculations.)
AVR = respiratory rate x (TV - dead air volume)
AVR = 32 breaths/min x 350mL
AVR = 11,200 mL/min
You are assessing a patient admitted to the hospital with pneumonia. They are breathing
at a rate of 30 breaths per minute. What is their Alveolar Ventilation Rate? (show your
calculations.)
AVR = respiratory rate x (TV - dead air volume)
AVR = 30 breaths/min x 350mL
AVR = 10,500 mL/min
4. List TWO reasons why we measure pulmonary ventilation? *Note: The student only has
to provide two reasons
1. To assess pulmonary function
2. To assess severity of pulmonary disease
3. To monitor improvement or deterioration of a diseases process
