Which stomach compartment is the true stomach, absorbing nutrients before passing to intestines?

Explanation:
The key idea is that the true stomach is where the chemical digestion with acid and enzymes happens. The abomasum functions like a monogastric stomach, secreting hydrochloric acid and pepsin to digest proteins and prepare the chyme for the small intestine. The rumen and reticulum are fermentation chambers where microbes break down fibrous material, while the omasum mainly grinds and absorbs some water and minerals before the digesta reaches the true stomach. After the abomasum digests the protein, the chyme moves to the small intestine where most nutrient absorption occurs.
