This is a 3d model of a Human Small and Large Intestines Anatomy. Complete with color and bump maps.
The intestines are a long, continuous tube running from the stomach to the anus. Most absorption of nutrients and water happen in the intestines. The intestines include the small intestine, large intestine, and rectum.
The small intestine - Its job is to absorb most of the nutrients from what we eat and drink. Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum.
The large intestine - The colon absorbs water from wastes, creating stool. As stool enters the rectum, nerves there create the urge to defecate.
