how does the large intestine absorb water
These vitamins are absorbed by the large intestine along with some ions, but the chief product absorbed by your large intestine is water. Water reabsorption is a main function of the large intestine. It can absorb 300 ml, or about a cup and a half, of water a day. This water removal dries out the feces. If food moves through the large intestine too quickly, it will not have sufficient time to absorb water, which will result in the passage of watery stool, or diarrhea. By contrast, when food residue remains in the large intestine for an extended period of time, too much water can be absorbed.
Even though the colon is also known as the large intestine, itâs actually only between 3 and 5 feet long, but itâs wider than the small intestine. Anything that wasnât absorbed in the small intestine will move into the large intestine, mostly fiber, bacteria and water. The large intestine basically has 3 jobs: Absorbs Water: A healthy colon absorbs 80% of the water that passes through it. The longer food sits in the colon, the more water is absorbed which means constipation. Not good.
