What is the main job of the large intestine after nutrients are absorbed in the small intestine?
Answer
Absorb much of the remaining water and electrolytes before compaction
The digestive process involves sequential steps where different sections of the tract handle specific tasks. Following the absorption of nutrients in the small intestine, the remaining material—which includes undigested matter, water, and bacteria—transfers to the large intestine. The large intestine’s critical function at this stage is primarily conservation and preparation for output. It actively reabsorbs a significant portion of the remaining water and essential electrolytes back into the body. This process allows the waste residue to undergo compaction, transforming it into feces suitable for eventual elimination.
