In between a monogastric and a polygastric. Can digest roughages the way a polygastric can but has 1 stomach. Mouth starts the breakdown process, the esophagus continues the process using saliva, the stomach churns the food and uses acids to break it down, small intestine absorbs nutrients. > duodenum > liver > gall bladder > small intestine > ceca (appendix) > large intestine > cloaca > vent. Mouth > esophagus > rumen > reticulum > omasum > abomasum > small intestine > large intestine > rectum > anus. Chew and swallow food bring it back up and chew and swallow again. Digest cellulose > vfa = volatile fatty acid. Esophageal groove > pathway directly to abomasum. Bile- produced in liver, stored in gall bladder.
