What is one of the main functions of the large intestine?

The large intestine primarily functions to reabsorb water and eliminate waste from the body. As food passes through the digestive system, the small intestine absorbs the majority of the nutrients. By the time the remaining material reaches the large intestine, it mainly contains undigested food, bacteria, and waste products. The large intestine's role is crucial as it extracts water from this material, thus helping to form solid waste (feces) for elimination. This process is vital for maintaining fluid balance in the body and preventing dehydration. Additionally, by effectively removing waste, the large intestine plays an important role in digestion and overall health.
