Abstract

There is no literature regarding the comparative descriptive variations of the lungs in the non-flying and flying ducks that could adapt various functions, such as flying and running. This study was conducted to reveal a gross morphological description of the lungs and bronchial system of adult ducks (domestic and migratory) of both sexes, Pekin ducks (Anas platyrhynchos) and Pintail ducks (Anas acuta). The anatomy of the domestic and migratory duck’s lungs was studied macroscopically and by corrosion cast technique. The number of the secondary bronchi of the investigated species. We found (4-5) MV, (7-9) LD, (2-4)LV, and (36-40) PO secondary bronchi In the Pekin duck, 4 MV, 10 LD, 4 LV, and (38-44) PO secondary bronchi in the Pintail duck. Results obtained by this study may be used as the basis of a structural and functional study of avian respiratory. Understanding the morphological characteristics of the lungs of the ducks, especially the migratory ducks, might have a crucial role in the distribution of avian influenza virus and can be responsible for avian flu in the Middle East region.
