The digestive system is very important to the body. Without it, we would not be able to live. It is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.

Every day more than 1.5 liters are used to do that.When food particles leave the stomach, they are only about one millimeter in size. From the stomach, the food now moves to the small intestines. More enzymes are added here from the pancreas to help to further break down food. On top of that, the gallbladder releases bile which it had stored from the liver earlier. The bile is used to mainly break down fats. The trip through the small intestines involves going through 22 feet of tubing. All throughout the small intestines, there are small villi, which are hair-like projections. Each of these are covered with microvilli.
