The correct sequence of the passage of feed through the digestive system of a ruminant is
Answer Details
Ruminants are mammals that have a four-chambered stomach specialized for digesting tough plant materials. The passage of feed through the digestive system of a ruminant begins in the rumen, where bacteria and other microorganisms break down the plant material through fermentation. The partially digested feed then passes into the reticulum, where it is regurgitated and rechewed (cud), before being swallowed again and passed through the omasum, which absorbs water and some nutrients. Finally, the feed enters the abomasum, which is the true stomach of the ruminant and functions like the stomach of other mammals, secreting acids and enzymes to further break down the feed. Therefore, the correct sequence of the passage of feed through the digestive system of a ruminant is rumen → reticulum → omasum → abomasum.
