1. The abomasum (D) is the true stomach of ruminants where digestive chemicals (like gastric juices) are added for chemical breakdown of food, similar to the monogastric stomach.
2. The rumen (B) is the largest compartment of the ruminant stomach and contains microbes (bacteria, protozoa) that ferment and break down fibrous plant material.
3. The reticulum (A) has a honeycomb - like structure and functions to sort feed particles and trap foreign objects (like nails, wire) that the animal might have ingested.
