ABSTRACT:

Histogenesis of human fetal lung was studied in 40 human fetuses under light microscope after sectioning and staining with hematoxylin & eosin stain, in fetuses with gestational age ranging from 10 weeks to fetuses above 30 weeks. Appearance of various levels of bronchi were identified with the changes in the epithelium at different levels of bronchi. The appearance of alveolar ducts and few alveoli were recognized after 25 weeks of gestation. Vascularisation of the fetal lung was observed as early as 10 weeks of gestation. Appearance of various levels of bronchi were identified with the changes in the epithelium at different ages of gestation.

Key words: Fetal Lung, Bronchi, Respiratory Distress, Alveolar Ducts, Alveoli.
