The digestive system of the capybara has been investigated because its coprofagia habits, important for their absorptive activity. These species present differences in terms gastrointestinal morphological characters when compared with other rodents. Macroscopiclly, stomach is constituted following parts: cardiac, pyloric, body, fundic and gastric diverticulum. It presents two curvatures, one big another small. Externally, presence bands (tenias) observed. With regards to volumetric view, capacity varies from 850 2010 ml, an average 1498.57 ml. So, this animal can be classified as a simple stomach, format curved sack similar inverted letter 'J'. mucous membrane surface filled by numerous tortuous folds longitudinally distributed along all extension. tunic also possesses recesses located among successive folds, which were denoted parts openings described pits. In cardiac part, glandular epithelium glands noticed containing lot parietal neck cells. body diverticulum contain proper main, Finally, pyloric part cellular types,
