Quizplus · Accepted Answer

The mucosa of the small intestine has millions of tiny finger-like structures called villi. The villi increase the small intestine's ability to absorb nutrients by increasing the surface area of the mucosa. The jejunum is a region of the small intestine. The submucosa lining contains the blood vessels and nerves that supply the digestive tract. The rugae are folds in the muscle layer of the stomach and can hold more food.
