Once the stomach has performed its part of the process and absorbed as much of the food as it can it passes the ingesta on to the
small intestine, which in turn passes it to the large intestine (Stevens 2008). While the ingesta travels through the small intestine the
majority of what will be absorbed in the entire digestive process is absorbed (Stevens 2008). The nearly twenty foot long tubes of the small
intestine are lined with a permeable layer that will allow carbohydrates and proteins to be absorbed by the organism and subsequently
transported wherever they are needed in the body (Parsons 2008). Beyond the fermentation of small amounts of cellulose-based
organic material in the caecum the large intestine serves to transport waste to the anus where it can be expelled (Wolin 1981).
