The structural components of a fish’s digestive system include the mouth, teeth and gills, esophagus, stomach, pylorus, pyloric cecum, pancreatic tissue, liver, gallbladder, intestine, and anus. The esophagus, which is lubricated by mucus, leads to the stomach.
The stomach of omnivorous and planktivorous fish, if present, is small because a more or less constant flow of small food particles can flow directly into the intestine. In fish, the pancreas is usually diffuse, not a discrete body. As in all vertebrates, the pancreas has two digestive functions.

Once food is chewed and mixed with saliva, it passes through the mouth, pharynx, and then esophagus to the stomach. The stomach is a muscular organ responsible for storage, which initiates the breakdown of nutrients and passes the digesta to the small intestine.
The stomach has four distinct areas that include the esophageal, cardiac, fundic, and pyloric regions. The esophageal region is located at the entrance of the stomach from the esophagus.
