During the human digestion process, digestion is compartmentalized in various organs throughout the digestive system. how does this system work

The human digestion starts in the small intestine gets the most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use.  When food enters the small intestine, villi along the intestine wall along with enzymes help break down the food, and takes a long journey. The stomach is right above the small intestine, and the small intestine is all wrapped around, and isn't that thick. Nutrients from the food are released to the whole body as energy. The small intestine brings the food to the large intestine, which is five feet long and is near your pelvis, or hips. The large intestine connects to the rectum, and then to the anus. In the large intestine, all the water is absorbed as well as salt.
