Final answer:
Unabsorbed water and undigested remains of chyme enter the colon after passing through the ileocecal sphincter, leading to the formation of feces in the large intestine.
Step-by-step explanation:
After moving through the ileocecal sphincter, unabsorbed water and undigested remains of chyme enter the colon, which is part of the large intestine. This part of the digestive system is responsible for absorption of the remaining water and conversion of the liquid chyme residue into semisolid feces. The large intestine's functions involve the absorption of water and electrolytes, feces formation, and eventual defecation. The colon houses intestinal flora that aid in the final digestion process, and the feces are stored in the rectum until they are eliminated through the anus.
