Histological And Histochemical Studies of The Lung of developing one-Humped Camel( camelus Dromedarius)

The current work was carried out on the lungs 105 dromedary foetuses, be,sining from one cm CVRL.) dayo ) untill 120cm CVTIL (393.4 dnyu ) , At I-Jcm CVHL (68.3-73.7 days), the foetal m the one humped camel was consisted of epith-Blyzed tubules lined with stratified columnar epi-lium (prospective bronchial tree) which were embedded_ The latter was condensedture muscle coat) around these tubules.
