Which of the following statements is true?

a) Closing capacity exceeds functional residual capacity during infancy, but reaches adult values at 1 year.

c) Flatter diaphragm and horizontal ribs limits expiratory reserve volume in infants

d) Major site of airway resistance in younger children is the medium-sized bronchi.

Answer

Answer d.

Closing capacity exceeds FRC until approximately 6 years of age. Infants have poor lung compliance and high chest wall compliance. Flat diaphragms and horizontal ribs decrease inspiratory reserve volume, not expiratory reserve volume, in infants. Of the available options, only D is correct.
