Which part of the digestive tract is chiefly responsible for reclaiming water and electrolytes from indigestible food residue and forming semi-solid feces before elimination?
Large intestine (colon)
Stomach
Gallbladder
Small intestine
The large intestine (colon) absorbs the remaining water and electrolytes from indigestible chyme, houses gut flora that further break down material, and compacts the waste into stool for eventual elimination. The stomach primarily performs mechanical and chemical digestion; the small intestine absorbs most nutrients; the gallbladder stores and concentrates bile but does not absorb water from food.
