This chamber controls what is able to pass into the abomasum. Eggs from mature females in the abomasum are passed in the faeces. The reticulum is adjacent to the diaphragm, lungs, abomasum, rumen and liver. Chymosin is produced by ruminant animals in the lining of the abomasum. These are the rumen, reticulum, omasum, and abomasum. Herbivores have evolved cecums (or an abomasum in the case of ruminants). The enzyme lysozyme has adapted to facilitate digestion of bacteria in the ruminant abomasum. The omasum comes after the rumen and reticulum and before the abomasum. This allows milk to pass by the reticulorumen straight into the abomasum. Laguna "kesong puti" traditionally use rennet from carabao or cow abomasum. After this, the digesta is moved to the true stomach, the abomasum. Inserting a toggle in addition to rolling has shown significant reduction in the abomasum relapsing. To reclaim these nutrients, the ruminant then digests the bacteria in the abomasum. A gas-filled abomasum can move into an abnormal location and become displaced. The infective larvae pass through the first three stomach chambers to reach the abomasum.
