Digestive system of a pig
The digestive system of pigs is an intricate network of organs developed for effective nutrient digestion. After entering the mouth, where teeth make grinding easier, food passes down the esophagus and into the monogastric stomach, where it is broken down and digesting enzymes are secreted.
With the help of bile and pancreatic enzymes, the duodenum, jejunum, and ileum, which make up the small intestine, are vital for the absorption of nutrients. While the colon and rectum collect water to generate feces, the cecum, a portion of the large intestine, aids in the fermentation of fiber. By using this method, the pig is guaranteed to obtain vital nutrients from its omnivorous diet.
