N2  - The stomach of balady duck (Anas platyrhnchos) was demarcated into upper part or the gastric (proventriculus) and the lower part or the muscular stomach (gizzard); connected together by isthmus. The pyloric region was a very small area between the gizzard and duodenum. The tunica mucosa of the proventricular wall showed longitudinal branched folds (plicae) separated from each other by sulci. The simple columnar epithelium lining the excretory ducts of the submucosal proventricular glands were positively reacted with PAS, alcian blue, PAS- alcian pH 2.5 combinations and Best's carmine; while, the secretory unites reacted negatively with these stains. The proventricular glands were lined with oxyntico-peptic cells. Ultrastructurally, the oxyntico-peptic cells were demarcated into light and dark alveolar cells. The mucosal folds of the middle gizzard were lined by simple columnar epithelial cells covered by an internal membrane; koilin. The propria submucosa was occupied by numerous simple branched tubular glands lined by simple cuboidal epithelium
