Abstract

In the current study use ten of the laughing dove (Streptopelia senegalensis) birds from both sexes, the body weight was (102.811±3.599gm). The present study include the morphometric features of the trachea, primary bronchi and lungs. The trachea was appear long flexible tube consist from several number of the cartilage rings closed like (O) shape which refer to the basic unit structure of the trachea. The mean length of the trachea was (6.166±0.176 cm) and this form (66.544 %) from the total length of the respiratory system. The primary bronchi appear as short tubes consist from several number of cartilage rings has (C) shape open from the medial side, connected together by transparent membrane. The length of right and left primary bronchi was ( 5.6 ± 0.4 mm ) ( 6.6 ± 0.2 mm ) and this form (6.043 %) (7.122%) respectively from the total length of the respiratory system. The lungs was pink into light red color, triangular or pyramidal-shaped. Each lung consist from two surfaces costal and visceral surfaces and three borders were lateral, medial and posterior borders. In the costal surface can be seen the lung contain five impressions. The length of the right and left lungs were ( 1.633 ± 0.02 cm ) ( 1.533 ± 0.03 cm ) and this form low percentage from the length of the respiratory system reaches into (17.623 %) and (16.544 %) and the thickness of right and left lungs were (4 ± 0.44 mm) (4.6 ± 0.49 mm), while the weight of the right and left lungs was (0.325 ± 0.032 gm) (0.308 ± 0.018 gm) respectively.
