The camel possesses a multilocular compound stomach which occupies the whole left half of the abdominal cavity and extends a little to the right of the median plane. The stomach comprises the rumen, reticulum, omasum and abomasum.
The rumen extends from a level with the cranial border of the 7th rib till the pelvic inlet. Its parietal surface related to the left abdominal wall, spleen and left kidney and presents the faint left ruminal groove. The visceral surface is related to the other compartments, liver, trans verse and descending colon and presents the cranial, middle and caudal right ruminal grooves. These grooves demarcate the medio- and cranio ventral glandular sacs. The reticulum and omasum are situated in the right side of the intrathoracic part of the abdominal cavity from the level of the 7th till the 9th rib. The reticulum is separated from the diaphragm by the omasum, while the omasum comes into relation with the liver and diphragm laterally and the rumen medially. The abomasum is situated in the right side from the level of the 9th till the 12th rib and related laterally to the liver and medially to the rumen. The gastric groove is represented by a ruminal and reticular parts extending from the cardia till the reticulo-omasal-orifice.
