11. Remember our digestion diagram? Where is water used?

12. The Scoop on Poop • The useable nutrients are absorbed into the bloodstream from the small intestine. • The leftover material continues on to the large intestine, where fecal matter (feces, or “poop”) is created. The large intestine absorbs water and some electrolytes from the leftover material, and that water is returned to the body to prevent dehydration. • If too much water is absorbed, constipation occurs; if too little water is absorbed, diarrhea occurs. • Once the feces are created, they pass to the colon, where they are stored. When the colon is full, a signal is sent to your brain telling you that you need to relax your anal sphincter and release the feces.
