Abstract: The study aimed to investigations of the, histological structure, in the lung of local Iraqi Muscovy ducks. Five adult Muscovy ducks were used in this study, regardless of their sex. After dissection, the lungs were removed and rinsed with tap water to remove any impurities. Samples measuring 1 cm³ were taken from the lung lobes and the sample was fixed by using (10% formalin), for 48 hours. Following complete fixation, the (routine histological techniques) were applied for microscopic examination. The results showed that the bronchioles were lined by pseudo stratified columnar ciliated epithelium, supported by hyaline cartilage and connective tissue, with a prominent thick layer of smooth muscle fibers. Each terminal bronchiole branched into two or three respiratory bronchioles, which were lined by simple ciliated cuboidal cells along with some non-ciliated cells. The wall of the (respiratory bronchioles) were ramifies inside the alveolar sacs and the alveolar ducts, where the epithelium transitioned to simple squamous epithelium.
