Which compartment receives feed from the omasum and passes it to the small intestine?

• A. Rumen
• B. Reticulum
• C. Abomasum
• D. Omasum

Answer: (D)

In this part of digestion, the journey of ingesta through the ruminant stomach shows distinct roles for each compartment. The omasum, with its many folds, primarily concentrates and mechanically processes material, absorbing some water and volatile fatty acids before the content moves on. The next stop is the abomasum, the true stomach, where acidic gastric secretions and enzymes begin the chemical digestion of proteins and other nutrients. From there, the chyme enters the small intestine for the final stages of digestion and nutrient absorption. So, the compartment that receives material from the omasum and passes it to the small intestine is the abomasum. The rumen and reticulum are the fermentation chambers, and the omasum sits between them and the abomasum to prepare the ingesta for true gastric digestion.
