How many compartments does a cow's stomach have?

Explanation:
Four compartments characterize a cow's stomach, showing how ruminants digest tough plant material. The four sections are the rumen, reticulum, omasum, and abomasum. In the rumen and reticulum, microbes break down cellulose through fermentation, turning fibrous feed into usable nutrients. The omasum helps absorb water and minerals and further reduces particle size. The abomasum acts as the true stomach, using acid and digestive enzymes to break down proteins. This setup explains why there are four compartments rather than two, three, or five: each stage serves a distinct role in breaking down, processing, and digesting the feed.
