This first compartment acts as a 'hopper-like' container. Dorsal regions have stratified squamous epithelium and are non-keratinized whilst ventral regions (glandular saccules) are lined by mucinous epithelial cells. There are no papillae present in C1. C1 is thought to be involved in absorption of water and solutes, but is not thought to play a role in bicarbonate formation. The contents of C1 are homogenous and fibrous and there is no dorsal gas cap as can be seen in ruminants. A single walled [[Oesophageal Groove|oesophageal groove]] is present.

This first compartment acts as a 'hopper-like' container and is most comparible to the rumen, although with some notable differences.
