14. The Large Intestine The parts of your cheeseburger and pear that are not absorbed in the small intestine move by peristalsis into the large intestine, also called the colon. The large intestine, shown in figure 8, has a larger diameter (about 5cm) than the small intestine. However, at about 1.5 m long, it is much shorter than the small intestine. Most of the water in the ingested foods and liquids is absorbed in the small intestine. As food travels through the large intestine, even more water is absorbed. Materials that pass through the large intestine are the waste products of digestion. The waste products become more solid as excess water is absorbed. Peristalsis continues to force the remaining semisolid waste material into the last section of the large intestine, called the rectum. Muscles in the rectum and anus control the release of this semisolid waste, called feces.

15. Bacteria and Digestion You might think that all bacteria are harmful. However, some bacteria have an important role in the digestive system. Bacteria, such as the ones shown in Figure 8, digest food and produce important vitamins and amino acids. Bacteria in the intestines are essential for proper digestion.
