From Embryology
Stage Human Mouse Features
Embryonic week 4 to 5 E9 to E11.5 lung buds originate as an outgrowth from the ventral wall of the foregut where lobar division occurs
Pseudoglandular week 5 to 17 E11.5 to E16.5 conducting epithelial tubes surrounded by thick mesenchyme are formed, extensive airway branching
Canalicular week 16 to 25 E16.5 to E17.5 bronchioles are produced, increasing number of capillaries in close contact with cuboidal epithelium and the beginning of alveolar epithelium development
Saccular week 24 to 40 E17.5 to PN5 alveolar ducts and air sacs are developed
Alveolar late fetal to 8 years PN5 to PN28 secondary septation occurs, marked increase of the number and size of capillaries and alveoli
