How many chambers does a cow's stomach have?

Options

A. One
B. Two
C. Three
D. Four

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of a Cow's Stomach**:
- A cow has one stomach, but it is divided into four distinct compartments.

2. **Identifying the Four Compartments**:
- The four compartments of a cow's stomach are:
1. **Rumen**: This is the first compartment where the cow initially stores the grass it swallows without chewing. It is also where microbial fermentation begins.
2. **Reticulum**: This second compartment helps in processing roughage and works closely with the rumen.
3. **Omasum**: The third compartment absorbs moisture and has a larger surface area for efficient absorption.
4. **Abomasum**: The final compartment functions similarly to a human stomach, releasing enzymes to digest proteins and starches.

3. **Digestive Process**:
- The cow's digestive process involves regurgitating food from the rumen to chew it again, which aids in breaking down the food further before it moves to the next compartments.

4. **Conclusion**:
- Therefore, the answer to the question is that a cow's stomach has **four chambers** or compartments.
