What are the principal functions of the large intestine as described in the chapter?

The principal functions of the large intestine are to absorb most of the remaining water from indigestible food residue, store feces, and eliminate waste from the body.

The large intestine plays a crucial role in processing waste material. It absorbs approximately 90% of the remaining water and sodium and potassium ions from the indigestible food residue, which helps to adjust the consistency of the waste material, forming feces. Additionally, it serves as a storage site for feces before elimination, and it is also home to beneficial bacteria that can produce vitamins for absorption by the body.
