Between the small intestine and the large intestine is a sphincter-type valve called the Ileocecal Valve (ICV). The purpose of this valve is to “prevent backflow” from the Large Intestine, once any material leaves the Small Intestine.
Not all the contents entering the digestive tube are going to be absorbed as food. In fact, much of what is ingested and processed continues to flow through the tube for eventual elimination. At the point where the small intestine ends, it sends its watery waste products into the large intestine.
IF things “are normal” the ileocecal valve:
Remains closed most of the time.
Opens briefly to let the contents of the small intestine exit.
Closes again quickly to prevent any materials in the large intestine from leaking back.
The vermiform appendix is, as the name implies, a wormlike, tubular structure. Although it serves no important digestive function in humans, it contains lymphatic tissue and may play a minor role in the immunologic defense mechanisms of the body. The appendix is directly attached to the cecum. The appendix contains a blind, tubelike interior lumen that communicates with the lumen of the large intestine 3 cm (1 inch) below the opening of the ileocecal valve into the cecum.
The ileocecal valve is a sphincter that separates the small intestine from the large intestine. It functions to control the flow of material into the large intestine.
