Villi also help the food to move along the digestive tract. Food takes three to six hours to move through the small intestine. The small intestine has three parts, the duodenum, jejunum and ileum.
The villi help to increase the total area on the outside of the small intestine to the size of. about half a tennis court. In this way, the villi help absorb, move, and distribute some of. the fluids and nutrients into the blood and lymphatic system.
