Formation of Waste
The villi in the large intestine cannot absorb some food products, such as dairy or cellulose. Such food products are mixed with other bodily waste products and compacted into hard, concentrated feces.
The large intestine passes the feces into the rectum, where it is stored for a period. After some time, the feces are eliminated through defecation, which involves the contraction and relaxation of the anus. The anal sphincter regulates the exit of the waste material.
