Numerous small lymph nodes are scattered in the grooves. The lymph drains to larger atrial nodes between the cardia and [[Omasum - Anatomy & Physiology|omasum]], then to the cistera chyli.

*Keratinised stratified squamous epithelium
*No glands
*Honeycomb appearance of short and tall folds
*Mucosal layer thrown into folds
*The folds gradually merge into papillae where the reticulum meets the rumen
*Lamina muscularis present as discrete bands of smooth muscle (not continuous)
*[[Tongue - Anatomy & Physiology#Types of Papillae|Conical papillae]], also called secondary papillae, on folds providing a rough surface to increase food breakdown
*2 thick layers of tunica muscularis- inner circular and outer longitudinal
*The upper keratinised layer protects against abrasion
*The deeper layers metabolise [[Volatile Fatty Acids|volatile fatty acids]]
