Which part of the ruminant stomach is recognized as the true stomach?

1. Rumen

2. Reticulum

3. Abomasum

4. Omasum

The correct answer is: Abomasum

The abomasum is recognized as the true stomach in ruminants. This part of the digestive system functions similarly to the stomach of non-ruminant animals, where the primary action is the secretion of gastric juices that contain enzymes and acids. This allows for the breakdown of proteins and the digestion of food, supporting the overall digestive process. In contrast, the other chambers of the ruminant stomach, such as the rumen, reticulum, and omasum, primarily serve different purposes in digestion. The rumen is involved in fermentation, breaking down fibrous plant materials with the help of microbes. The reticulum works closely with the rumen to facilitate the movement of food back to the mouth for further chewing, while the omasum primarily absorbs water and nutrients from the digested feed. Thus, the unique role of the abomasum sets it apart as the true stomach responsible for the chemical digestion of food.
