Beyond forming faeces, the large intestine reabsorbs water and electrolytes and hosts bacteria that synthesise vitamin K and some B-complex vitamins. …

Besides its role in forming and temporarily storing faeces, the large intestine performs two other important functions. First, its mucosa actively reabsorbs a large proportion of the water (and some sodium and other electrolytes) remaining in the material that enters it from the ileum, progressively converting the initially watery residue into firmer, semi-solid faeces -- an important contribution to the body's overall water economy, since several litres of fluid pass through the gut each day and only a small fraction is normally lost in the faeces. Second, the large intestine hosts a substantial resident population of bacteria, which, among their other activities, sy …

Recall the large intestine has NO digestive-enzyme role of its own -- its two other functions are purely reabsorptive (water/electrolyt …

Claiming the large intestine absorbs digested nutrients (glucose, amino acids, fatty acids) -- nutrient absorption is essentially complete by the time material reaches the large intes …
