The first chamber of the deer's stomach, the rumen, is used for food storage. This allows the deer to eat first and digest later.

The reticulum contains microorganisms that break down the plant parts through fermentation. The omasum extracts water from the processed food to keep the deer hydrated. The food then enters the final chamber, the abomasum, for further digestion before it moves on to the intestines.
