How is the small intestine designed to absorb digested food?

Explanation

### Step-by-Step Solution:

1. **Structure of the Small Intestine**: The small intestine is a crucial part of the digestive system where most of the digestion and absorption of nutrients occurs. It is long and coiled, providing ample space for digestion and absorption.

2. **Presence of Villi**: The inner lining of the small intestine features numerous tiny, finger-like projections called villi. These villi significantly increase the surface area of the intestinal lining.

3. **Increased Surface Area**: The primary function of the villi is to enhance the surface area available for absorption. A larger surface area allows for more efficient absorption of nutrients from the digested food.
