Final answer:
The large intestine processes undigested food into feces and absorbs water from the waste material before elimination.

The large intestine helps the body excrete wastes by processing undigested food into feces. It absorbs water from the remaining food matter, which helps in the formation of solid waste. The large intestine also plays a role in the reabsorption of electrolytes, vitamins, and water from the waste material before elimination.
