Final answer:
Feces in the colon are removed through the process of elimination, involving the reabsorption of water, peristaltic movements of the colon muscles, and elimination through the anus.
Step-by-step explanation:
The ways to remove feces in the colon are through the process of elimination. As undigested food material enters the colon, most of the water is reabsorbed. Peristaltic movements of the colon muscles move the semi-solid waste through the colon and store it in the rectum. When the rectum expands in response to the storage of fecal matter, neural signals trigger the urge to eliminate. Finally, the solid waste is eliminated through the anus using peristaltic movements of the rectum.
