Microscopic Studies Of The Foetal Lung Development In The OneHumped Camel (Camelus dromedarius) Obtained From Kano Abattoir

Eighty – seven foetal lung samples from camels (Camelus dromedarius) were collected at Kano abattoir to study lung development. Four phases of the lung development were observed as follows; pseudo-glandular phase was between 10.5 cm to 38.2 cm crown-rump length, with endodermal buds and prominent mesenchymal cells. Canalicular phase was observed between 38.7 cm to 62.2 cm crownrump length and was characterized by thinning of the endodermal buds and invasion of capillaries. Saccular phase was noticed at 65.6 cm to 82.6 cm crown-rump length when thick intercellular septa were noticed. Alveolar phase was noticed between 85.9 cm to 121 cm crown-rump length when primitive alveolar was noticed. This study has established phases of lung development in the camel and serves as baseline information for scientific knowledge.
