| The omasum is almost absent in chevrotains. |
| The rumen, reticulum and omasum can be compared to a kind of foregut fermentation chamber. |
| Food taken into the rumen is later regurgitated into the mouth and completely masticated, then swallowed again and passed to the reticulum, omasum, and abomasum. |
| The reticulum is connected to the spherical omasum by a short tunnel. |
| Cattle have one stomach with four compartments, the rumen, reticulum, omasum, and abomasum, with the rumen being the largest compartment. |
| In a shallow bath of a hearty brown sauce of ground nuts and red oil sat part of one of the four chambers of a cow's stomach, the rumen, or omasum, or perhaps the abomasum. |
