A rumen fistula is a surgically created entry to the rumen in the left flank of the ruminant, typically permanent and with a rubber or similar material device (a 'cannula') fitted to close it between times of use. It enables the rumen contents to be accessed, and the rumen wall to be viewed and biopsied. Surgically modified ruminants such as these are only found on research farms, where they are used to study rumen function. Looking in through the fistula, you can see the rumen contents and the rumen wall.
Ruminants have a compartmentalised stomach. There are 4 compartments, the rumen, reticulum, omasum and abomasum. A non ruminant does not have a compartmentalised stomach, the non ruminants stomach has similar fucntions to that of the abomasum in the ruminants
It is a symbiotic relationship.

The Omasum is the third chamber of the ruminant stomach. It contains many folds so which enables water to be absorbed from the digesta that came from the rumen. The omasum is typically located between the rumen and the abomasum.
