Humans have a digestive track long with many internal folds. The important function of the folds is to provide surface area to the intestines. Improve flow of blood out in the digestive tract. Increasing the surface area over which the nutrients can be absorbed during digestion. Provide a storage area for the food unit so it can be completely broken down.
