in which part of the gut is water absorbed from undigested food?

Water from undigested food is absorbed mainly in the large intestine (especially the colon).

Quick Scoop

  • The undigested food leaving the small intestine still contains a lot of water and minerals.
  • As this material enters the large intestine, its lining absorbs most of the remaining water and electrolytes, turning the liquid mass into more solid feces.
  • This water‑absorbing role is why the large intestine (colon) is described as the main site where water from undigested food is absorbed.
