Which is a function of the colon?

• A. Absorbs water
• B. Breaks down protein
• C. Produces insulin
• D. Secretes gastric acid

Answer: (A)

The colon’s main function is absorbing water and electrolytes from indigestible material, which helps form solid stool. It also houses bacteria that ferment fiber and produce lubrication, contributing to stool consistency. This is why absorbing water is the best choice. The other options involve other organs: breaking down protein occurs mainly in the stomach and small intestine with digestive enzymes; insulin is produced by the pancreas; gastric acid is secreted by the stomach. In ostomy care terms, remaining colon function helps form stool and regulate fluid balance, whereas bypassing or removing the colon can lead to more liquid output and higher fluid needs.
