In man it is about nine times as long as the distance from the crown of the head to the coccyx. In Ruminants, such as the cow and the sheep, the stomach is very large and divided into four chambers—the rumen or paunch, reticulum, psalterium or manyplies, and abomasum. Fig. 67.

(Fig. 67). The rumen and reticulum serve as mere storage cavities, from which the food returns to the mouth for thorough mastication, and then passes direct, by means of a groove in the esophagus, into the psalterium, and finally on to the abomasum. The latter is the true stomach, and is provided with gastric glands. In the camels the rumen and reticulum have connected with them pouch-like diver- ticula for the storage of water. The constricted openings of the pouches into the rumen or reticulum may be entirely closed by sphincter muscles. In man and the higher apes there is present an attenuated extension of the caecum known as the vermiform appendix. In the fetus of man it is proportionally longer than in the adult. In the herbivorous mammals, such as the cow and rabbit, the caecum is greatly enlarged, so as to play an im- portant part in digestion. In a few forms, such as the sloths, some Cetacea, and a few Carnivora, the caecum is absent. The lowest mammals, the Monotremata, resemble birds.
