b. Both sentences are false

c. Only the second sentence is truth

d. Only the first sentence is truth

11. a preterm infant has a surfactant deficiency. Without surfactant, many of the alveoli collapse at the end of each expiration, which lead to pulmonary failure. Which of the following changes is present in a preterm infant, compared with a normal infant?

Alveolar surface tension  vs. pulmonary compliance 


a. Decreased vs. increased 

b. Increased vs. no change 

c. Decreased vs. no change 

d. Increased vs. decreased


d. increased alveolar surface tension and decreased pulmonary compliance

--> as type II alveolar cells produce surfactant which decreases surface tension to prevent collapse of alveoli 

-> pulmonary compliance: is a measure of the lung's ability to stretch and expand (distensibility of elastic tissue)
