What is the definition of reticulum in cattle?

The reticulum is one of the four compartments of a cow's stomach, specifically the second chamber, following the rumen. It plays a critical role in the digestive process by collecting smaller digesta particles and facilitating the fermentation of feed. The reticulum also assists in the regurgitation process, allowing cattle to chew their cud. Its unique honeycomb structure helps trap foreign objects that the animal may accidentally ingest.
