The four basic types of digestive systems in animals are the monogastric, the avian, the ruminant and the pseudorumiant. The digestive system consists of the gastrointestinal tract, also called the gastrointestinal tract or digestive tract, and the liver, pancreas, and gall bladder. The gastrointestinal tract is a series of hollow organs joined together in a long, twisted tube from the mouth to the anus. The hollow organs that make up the gastrointestinal tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus.
The liver, pancreas, and gall bladder are the solid organs of the digestive system.

Animals have developed different types of digestive systems to help digest the different foods they consume. However, your cecum, an organ with pouches at the beginning of the large intestine that contains many microorganisms necessary for the digestion of plant materials, is large and is where forage is fermented and digested.
Accessory organs play an important role in the production and delivery of digestive juices to the intestine during digestion and absorption. The digestive enzymes of these animals cannot break down cellulose, but the microorganisms present in the digestive system can. You have nerves that connect the central nervous system, brain, and spinal cord to the digestive system and control some digestive functions. Once this process is complete, digestive juices take over the proventricle and continue with the digestive process.
When digesting proteins and some fats, the stomach lining must be protected from being digested by pepsin. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and other components of the National Institutes of Health (NIH) conduct and support research on many diseases and conditions. Working together, nerves, hormones, bacteria, blood, and organs in the digestive system digest the foods and liquids you eat or drink every day. The muscles of the small intestine mix food with the digestive juices of the pancreas, liver, and intestine and push the mixture forward for further digestion.
