The cecum or caecum (from the Latin caecusmeaning blind) is a pouch connected to the ascending colon of the large intestine and the ileum. Most herbivores have a relatively large cecum, hosting a large number of bacteria, which aid in the enzymatic breakdown of plant materials such as cellulose.1

It absorbs water from indigestible food matter and then passes useless waste material from the body.
water is absorbed vitamin k is produced and other nutrients are absorbed.
Water is absorbed from unusable, indigestible wastes (feces)
Chemical digestion of cellulose
small intestine, and water absorption occurs in the colon/large intestine
No digestion occurs in the large intestine; digestion is finished in the small intestine. In the large intestine absorption takes place, then the waste materials are egested.
large intestine (colon)
water is recovered

true
Water from food is absorbed by the body
The type of movement that occurs in the large intestine is called peristaltic action. This is a series of rhythmic contractions of smooth muscles that are in the walls of the intestines. The intestines are composed of many small pouches called haustra. And as peristaltic action continues, feces in the large intestine move from one haustra to another until it finally reaches the anal canal and anus. Then when the internal and external sphincters relax, the feces is expelled from the body.
Minor fiber digestion by bacteria goes on in the large intestine, and water is absorbed, but no major lipid/protein/carbohydrate digestion occurs. All of that goes on higher up in the system.
Yes, absorption in the small intestine occurs through the villi.
These process occur in the large intestine and colon
