Which stomach is the true stomach?

Explanation:
Abomasum is the true stomach because it is the glandular compartment where gastric secretions—hydrochloric acid and enzymes like pepsin—perform proteolytic digestion, similar to a nonruminant stomach. In ruminants, the rumen, reticulum, and omasum are primarily fermentation and mechanical processing chambers that prepare the feed but do not provide the main acid-pepsin digestion. The abomasum receives material after initial processing and continues digestion with gastric juice before moving chyme to the small intestine.
