Omasum and abomasum (stomach chambers), goat

Photograph of the omasum and abomasum, the last two chambers of a goat's stomach. A goat's stomach has four chambers: the rumen, the reticulum, the omasum and the abomasum. The omasum is characterised by rough sheet-like folds whereas the abomasum has softer folds. The omasum is where water is absorbed and the abomasum is the equivalent to the human stomach.
