#Unit 7. System Physiology – Animal
A preterm infant has a surfactant deficiency. Without
surfactant, many of the alveoli collapse at the end of each expiration, which
in turn leads to pulmonary failure. Which of the following sets of changes are
present in the preterm infant, compared to a normal infant?
