Which stomach absorbs water?

Which stomach absorbs water?

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

Answer: (D)

In the ruminant stomach system, each compartment has a specialized role. The omasum contains numerous folds (laminae) that maximize surface area, allowing efficient absorption of water (and minerals) as digesta passes through. This makes it the primary site for water absorption before the material moves on to the true stomach. The rumen and reticulum are mainly fermentation and mixing chambers, producing volatile fatty acids, while the abomasum acts as the true gastric stomach, digesting proteins with acid and enzymes. So, the omasum is best at absorbing water.
