It carries food from the mouth to the crop and from the crop to the proventriculus. This is accomplished by periodic contractions (peristalsis) instead of gravity. In addition to digesting and absorbing feedstuffs, the intestine is critical for water and electrolyte balance, endocrine regulation of digestion and metabolism, and immunity. The larger its internal surface, the greater its absorptive efficiency, and a spiral valve is one method of increasing its absorption surface. The main enzymes active in the fish stomach are Pepsins.

The junction between the stomach and the intestine is marked by a muscular valve. Once reaching the throat, food enters a short, often greatly distensible esophagus, a simple tube with a muscular wall leading into a stomach. The liver has no specific shape in fish and generally molds itself into the space around the stomach and the heart, however it has a tendency to reflect the fishs body shape being long and tin in eels and wide in rays and skates. The latter are throat teeth. The muscular layers that form the esophagus are closed tightly at both ends by sphincter muscles, to prevent food or liquids from leaking from the stomach back into the esophagus or mouth. However the musculature behind this movability is quite different in the two groups. 2006 Apr;209(Pt 7):1301-9. doi: 10.1242/jeb.02130. As with all animals, digestion in fish involves the breakdown of eaten food into its smaller component parts: amino acids, vitamins, fatty acids, etc. and transmitted securely. The buccal cavity (the empty space in an empty mouth) secretes mucus to aid in the swallowing of food, but there are no special organs involved, no salivary glands, and this mucus is a lubricant only. In those fish which have a gizzard, such as Shad, it is the place where digestion begins because as well as its muscular activity the gizzard also secretes digestive enzymes into the food. The esophagus has a rich blood supply and venous drainage. Manometry is a test that is commonly done to evaluate motility disorders of the esophagus. The primary function of your esophagus is to carry food and liquid from your mouth to your stomach. The esophagus is a hollow, muscular tube that connects the throat to the stomach.
