Macroscopic and morphometric studies of the extrapulmonary primary bronchi and lungs of the indigenous adult male pigeon (Columba domestica)‎

الملخص EN

Macroscopical account of the extrapulmonary primary bronchi and lungs in the ten of the indigenous adult male pigeons (Columba domestica) collected from the Diwanyia city markets.

It is expect that this work will provide a pivot for future research and subsequent clinical applications as regards the biology of the pigeons.

After complete bleeding the target organs recognized then the shape, position, dimensions of each specimen were record.

The building units of the pulmonary primary bronchi were C-shaped hyaline cartilages.

Medial bronchial wall connecting all cartilages ends together.

The mean length of right and left bronchi was (0.76 ± 0.04 cm) (0.64 ± 0.24cm) respectively.

Lungs appear as pyramidal-shaped brilliant pink color; extend from the first to the sixth ribs. Each lung contain three surfaces (costal, vertebral, and septal) the dorsal border of the costal surface contain six deep grooves origin by embedded the first to the sixth ribs lead to divided the lung to seven lobes.

The mean length of right and left lungs was (3.1 ± 0.66cm), while the mean width of right and left lungs was (3.1 ± 0.66 cm).
