What is the four compartments of small ruminants?

The four compartments of small ruminants are:

Rumen: The rumen is the largest compartment of the small ruminant's stomach and is where most of the fermentation of food occurs. It contains billions of bacteria, protozoa, and fungi that help break down plant material.

Reticulum: The reticulum is located just in front of the rumen and is connected to it by a large opening. It helps to mix and store food, and also absorbs some of the water from it.

Omasum: The omasum is located just behind the reticulum and is responsible for further breaking down plant material. It also absorbs water and some of the nutrients from the food.

Abomasum: The abomasum is the fourth and final compartment of the small ruminant's stomach and is where most of the digestion of food occurs. It contains gastric juices that help to break down proteins and other nutrients.
