qformation qof qa qcapillary qnetwork qaround qairway qpassages?
a. Pseudoglandular
b. Saccular
c. Alveolar

The qcanalicular qphase qfollows qthe qpseudoglandular qphase, qlasting qfrom qapproximately q17
qweeks qto q26 qweeks qof qgestation. qThis qphase qis qso qnamed qbecause qof qthe qappearance qof
