Lined with non ciliated simple epithelial tissue and secretes surfactant to diminish surface
tension - Answer Alveoli
Structural tissue changes occur as it branches over 23 times - Answer Bronchi
Contains muscular tissue that can constrict if stimulated - Answer Bronchioles
Considered to be apart of the upper respiratory tract
Only structure to contain both hyaline and elastic cartilage - Answer Larynx
The larynx is classified as which part of the respiratory tract? - Answer Conducting Zone and
Upper Respiratory tract
Which of the following is true? - Answer The uvula moves upward during eating/drinking to
close off the nasopharynx.
Justin suffers with flu like symptoms, including a severe cough and fever. His chest x ray shows
fluid in the inferior lobe of his left lung. Which of the following can you conclude? - Answer
Two of the above (Justin's respiratory rate will be elevated)
TV (tidal volume) - Answer 500 ml
IRV (inspiratory reserve volume) - Answer 3100 ml
ERV (expiratory reserve volume) - Answer 1200 mL
RV (residual volume) - Answer 1200 mL
Which of the following is not a part of expiration? - Answer Thoracic cavity volume increases
(inspiration)
, C. The external intercostal muscles move the sternum and ribs inward.
D. Air rushes out of the lungs into the atmosphere
All of the following limit lung compliance except? - Answer A. Thoracic cage ossification

In spirometric measurements, the difference between a volume and a capacity is - Answer A
capacity is determined by adding two or more respiratory volumes.
During your night shift at the local ER, a patient arrives with a knife wound to his left lung. The
patient complains of pain and gasps for air. What is the most likely diagnosis for his condition? -
Answer The patient is experiencing a pneumothorax (introduced air in pleural cavity)
Jospeh has a tidal volume of 200 mL, a residual volume of 1,200 mL, and a respiratory rate of 40
breaths/min. What would be the value of his alveolar ventilation rate (AVR)? - Answer 2,000
mL/min
AVR = - Answer RR x (TV-150)
What can you conclude about Josephs pattern of breathing? - Answer Jospeh is
hyperventilating
Which of the following is true? - Answer A. The exchange of HCO3 for CT across the RBC is
called the Bohr Effect.
B. Most CO2 in the blood is transported in the blood in the form of Carbaminohemoglobin.
C. Peripheral chemoreceptors of respiration are located in the medulla oblongata.
D. The dorsal respiratory group of the medulla oblongata controls normal expiration.
E. WE DO NOT NEED TO KNOW THE RESIDUAL VOLUME TO DETERMINE VITAL CAPACITY.
Hemoglobin: - Answer A. Is 100% saturated when four oxygen molecules are bound
