Cartoon showing the stages in development of human lung alveoli.

**Human Lung Stages**
Lung Stage	Human	Features	Vascular
Embryonic	week 4 to 5	lung buds originate as an outgrowth from the ventral wall of the foregut where lobar division occurs	extra pulmonary artery then lobular artery
Pseudoglandular	week 5 to 17	conducting epithelial tubes surrounded by thick mesenchyme are formed, extensive airway branching	Pre-acinar arteries
Canalicular	week 16 to 25	bronchioles are produced, increasing number of capillaries in close contact with cuboidal epithelium and the beginning of alveolar epithelium development	Intra-acinar arteries
Saccular	week 24 to 40	alveolar ducts and air sacs are developed	alveolar duct arteries
Alveolar	late fetal to 8 years	secondary septation occurs, marked increase of the number and size of capillaries and alveoli	alveolar capillaries
embryonic stage - pseudoglandular stage - canalicular stage - saccular stage - alveolar stage Links: Species Stage Comparison \| respiratory
