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.
Absorption is the movement of digested food molecules through the wall of the intestine into the blood or lymph. The small intestine is the region where digested food is absorbed. Most absorption happens in the ileum. This is the longest part of the small intestine and is between 2-4 metres long. The small intestine has a large internal surface area for absorption to happen quickly and efficiently.
