Question
### Ruminant Digestive System

**Instructions:**
Place these organs in the correct order as they are located in the ruminant.

1. **Rumen**
2. **Omasum**
3. **Reticulum**
4. **Abomasum**

**Explanation:**
The ruminant digestive system consists of a series of specialized compartments. Understanding the order and function of these compartments is crucial for studying ruminant physiology.

**Order of Organs in the Ruminant Digestive System:**

1. **Rumen**: The largest stomach compartment, which acts as a fermentation vat. Here, microbes break down fibrous plant material into volatile fatty acids, gases, and microbial protein.
   
2. **Reticulum**: Often called the 'honeycomb', it catches any foreign objects ingested by the animal. It works closely with the rumen to mix the ingesta and aid in regurgitation.
   
3. **Omasum**: Known as the 'book stomach' due to its many leaf-like folds, it absorbs water and other nutrients from the digested contents, squeezing out liquid from the food.
   
4. **Abomasum**: The true stomach, similar to a monogastric stomach, where the acid and enzyme secretion occurs to further digest the nutrients before they pass to the intestines.

This order ensures effective digestion and nutrient absorption essential for the ruminant's health and productivity.
