The stomach has pylorus and this gets united with small intestine, which also has outlet through bile duct and pancreatic duct. The small intestine is followed by large intestine.
In basic cat anatomy, small intestine is most important due to its significant physiological function. The food from mouth is passed on to the esophagus and then, it enters into the cardia, then into the body of stomach. From pylorus of stomach, entry of food materials is straight to the duodenum, which is followed by the jejunum, ileum and finally, the intestinal segments.
