Reticulum of a goat

Reticulum of a goat

This image shows the reticulum of a goat. The reticulum is one of the four chambers of the ruminant (cattle, goats, sheep) stomach and is characterised by the honeycomb pattern which lines the inside. Bacteria are present here which causes fermentation of the food material. The oesophagus can be seen entering the reticulum at the top of the picture. The opening in the centre leads to the omasum, another chamber of the stomach. A small part of the rumen, another chamber, is attached to the reticulum on the right. The lining changes here to small papillae, and resembles carpet.
