### Step-by-Step Solution:

1. **Identify the Structure**: The ileum is the last part of the small intestine. It connects the small intestine to the large intestine.

2. **Understand the Function**: The ileum plays a crucial role in the absorption of nutrients. It is primarily responsible for absorbing vitamins, minerals, and other nutrients that were not absorbed in the earlier parts of the digestive system.

3. **Key Nutrients Absorbed**: Important nutrients absorbed in the ileum include vitamin B12, various salts, and other essential minerals.

4. **Recognize the Characteristics**: The ileum is characterized by the presence of:
- **Peyer’s patches**: These are small masses of lymphatic tissue that play a role in the immune response.
- **Villi**: These are small, finger-like projections that increase the surface area for absorption, enhancing the efficiency of nutrient uptake.

5. **Conclusion**: Therefore, the ileum is characterized by the presence of Peyer’s patches and villi.

### Final Answer:
