The intricate process of lung development begins at about 4 weeks’ gestation and consists of 6 discrete phases: (1) the embryonic stage (4–7 weeks’ gestation); (2) the pseudoglandular stage (5–17 weeks’ gestation); (3) the canalicular stage (16- to 26-weeks’ gestation); (4) the saccular stage (24- to 38-weeks’ gestation); (5) the alveolar stage (36-weeks’ gestation to 2 years of age); and (6) microvascular maturation (birth to 2–3 years of age).1 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/20 UR - accesspediatrics.mhmedical.com/content.aspx?aid=1109793468 ER -
