Extended data:

Rumination mainly occurs in some herbivores of Artiodactyla. Stomach of Artiodactyla (cattle, sheep, deer, etc.). ) is divided into rumen, reticulum, flap stomach and abomasum. The first three stomachs have no gastric glands, and their overall functions are fermentation, filtration, grinding and rough absorption of nutrients. Only abomasum is the part that secretes gastric juice, which is equivalent to monogastric animals, also called abomasum.

The rumen volume is 100-300 liters, accounting for about 80% of the four stomachs. Rumen contains a large number of microorganisms, including protozoa (mainly ciliates) and bacteria. Rumen itself does not secrete enzymes, and all enzymes in rumen are produced by microorganisms. The omentum is in front of the rumen, against the diaphragm and liver. The inner wall of the reticular structure is honeycomb, and microbial digestion is also carried out in the reticular structure.
