The present work includes anatomical and histological studied of the different part of the duodenum in the Goose (Anser anser).

It was taken (10) birds were anaesthesia and work of a longitudinal incision in the abdomen and the eradication of the gut complete manner and then duodenum measurements, Anatomical study shown duodenum divided into three parts ascending, descending and middle part.

Histological study after dying in the form of hematoxylin and eosin represent the wall of the duodenum in all parts consist of four-layer tunica mucosa, submucosa, muscularis and serosa.

The tunica mucosa of all parts of the duodenum was studied with folded villi of different shape and size, which were lined by simple columnar epithelium having more goblet cells in proximal part in contrast middle and distal part.

The goblet cells are distributed between enterocytes and secrete mucus that covers the mucosa.

The apical part of villi of proximal duodenum were slightly pointed and the basal parts of villi were thicker than middle and distal duodenum that’s come from the proximal part of duodenum plays major role in net nutrient absorption Lamina muscularis mucosa is various in thickness in all parts of duodenum and was made up of smooth muscle fibres.

Tunica submucosa in the duodenum of goose in this study consist of loose connective tissue rich with lymphoid fibres and duodenal glands.

The musculosa layer consists of two smooth muscle layers outer longitudinal layer and a thick circular muscle layer that allow mixing and propulsion of the digesta through the intestinal tract
