it is peristalsis
Materials that are not digested move into the large intestine, which is a shorter tube than the small intestine. The large intestine absorbs water and electrolytes from the remaining indigestible food matter and compacts it into feces for elimination.
It is digested by the acids in your stomach and then moved to your small intestine. In the small intestine the broken down food is carried into your bloodstream. The bigger food molecules move to your big intestines where the indigestible food molecules get their water absorbed by the larg intestine. After all that, it comes out as faeces.

absorption
Movement of food through the large intestine is caused by smooth muscle contraction called "peristalsis" the best way to describe this is to imagine how a snake moves its abdominal muscles to move.
Food enters the small intestine first. It enters the duodenum in the small intestine.
Well the nutrients that can't be digested and absorbed in the small intestine move on to the large intestine. The water is reabsorbed out of it and then moves down to the colon. When the bowels move the feces are egested via the rectum and anus.
