Answer

**Step-by-Step Solution:**

1. **Identify the Parts of the Small Intestine:**
The small intestine is divided into three distinct parts. To answer the question, we need to identify these parts correctly.

2. **First Part - U-shaped:**
The first part of the small intestine is U-shaped and is called the **duodenum**. It connects the stomach to the small intestine and is the initial segment where a lot of digestion occurs.

3. **Second Part - Long Coiled Portion:**
The second part of the small intestine is a long coiled section known as the **jejunum**. This part is responsible for the majority of nutrient absorption.

4. **Third Part - Highly Coiled:**
The last part of the small intestine is highly coiled and is referred to as the **ileum**. This section continues the absorption process and connects to the large intestine.

5. **Final Answer:**
Therefore, the three parts of the small intestine are:
- U-shaped: **Duodenum**
- Long coiled middle portion: **Jejunum**
- Highly coiled: **Ileum**
