Explanation:
The small intestine is the portion of the digestive tract that connects the stomach and the large intestine. The small intestine consists of three different parts: the duodenum, jejunum and ileum. The small intestine contains small finger-like projections of tissue called villi which increase the surface area of the intestine and contain specialized cells that transport substances into the bloodstream. Although these villi do not aid in the digestion of nutrients, they do help with nutrient absorption.
