Title: Late terminal sac period of developing lung
Description:
Stain hematoxylin-eosin, human fetus. Cross-sections of a bronchus (1) with cartilage rings (2) close associated with pulmonary arteries (3).
The alveolar appearance is evident, and the open spaces represent future alveolar duct systems as well as alveolar sacs. The cellular septa are still thick due to non-inflated and developing alveoli.
Keywords/Mesh: respiratory tract, lung development, fetus, terminal sac period, bronchus, pulmonary artery, cartilage, alveolus, histology, embryology, POJA collection
