Name three parts of epididymis.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Epididymis**: The epididymis is a crucial part of the male reproductive system, located at the back of the testes. It plays a significant role in the maturation and storage of sperm.

2. **Identifying the Parts**: The epididymis is divided into three main parts:
- **Caput (Head)**: This is the upper part of the epididymis. Its primary functions include fluid reabsorption and compacting sperm chromatin, which helps in increasing the density of the sperm fluid.
- **Corpus (Body)**: This is the middle section of the epididymis. It is involved in protein synthesis that aids in providing motility to the sperm. The corpus also secretes vesicles and small amounts of fructose, contributing to the nourishment and defense of the sperm.
- **Cauda (Tail)**: This is the lower part of the epididymis. It serves as the storage site for sperm and ensures the quality of the stored sperm.
