Large intestine: Immediately following the small intestine is the large intestine (aka colon), where the gut musculature gradually moves along any remaining digested and undigested compounds. Another unique habitat of gut flora microbiota reside in the large intestine (given that we nourish our body with microbe-friendly foods and supplements). Another important act is achieved in the colon: bulk. While significant amounts of water are absorbed from the gut into the bloodstream in the small intestine, "the final water absorption activity occurs in the colon, to functionally solidify the remaining indigestible components of our diet, creating stool," Ferira explains.
