Answer

To solve the question regarding the ileocecal valve and what it prevents the backflow of fecal matter from, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Ileocecal Valve**:
- The ileocecal valve is a muscular sphincter located between the small intestine and the large intestine.

2. **Identifying the Parts of the Intestine**:
- The small intestine is divided into three parts:
- Duodenum
- Jejunum
- Ileum (the last part of the small intestine)
- The large intestine consists of three parts as well:
- Cecum (the first part of the large intestine)
- Colon
- Rectum

3. **Function of the Ileocecal Valve**:
- The primary function of the ileocecal valve is to prevent the backflow of contents (fecal matter) from the large intestine back into the small intestine.

4. **Determining the Direction of Backflow**:
- Since the ileocecal valve is located between the ileum (small intestine) and the cecum (large intestine), it prevents the backflow of fecal matter from the cecum to the ileum.

5. **Conclusion**:
- Therefore, the ileocecal valve prevents the backflow of fecal matter from the cecum to the ileum. This corresponds to option two in the given choices.

### Final Answer:
The ileocecal valve prevents the backflow of fecal matter from the **cecum to the ileum**.
