الملخص EN

The aim of this study to show the histological and morphological feature of cells that consist the duodenal mucosa of local cows ,five samples of duodeni of each adult cows were used in this study ,the results of this study shows that the thickness of tunica mucosa and the length of villi increased gradually backward the ileum, while the depth of crypts of lieberkuhn decreased gradually backward the ileum, the thickness of muscularis mucosa was highest in the third part of the duodenum, Number of goblet cells decreased gradually toward the ileum, the length of goblet cells in crypts of lieberkuhn decreased in the third part of duodenum, while the length of these cells increased in villi in the third part of the duodenum .

The length of absorptive cells and goblet cells in crypts of lieberkuhn higher than their length in villi.

The conclusion of this study showed completed digestion processes and absorption processes happened in the first part of the duodenum and the absorption increased backward the ileum, therefore the thickness of tunica mucosa ,length of villi increased gradually backward the ileum ,Crypts of Lieberkuhen contained aged goblet cells and simple columnar cells while the villi contained young and active cells therefore the length of both cells in crypts of lieberkuhn higher than their length in villi of duodenal mucosa of local cows.
