Which statement about the transverse colon is correct?

• A. It stores urine
• B. It is never used for a stoma
• C. It is the largest/widest segment of the colon
• D. It has no role in ostomies

Answer: (C)

The important idea here is the anatomy of the colon and how its different parts relate to ostomy placement. The transverse colon is the widest part of the colon, with a relatively large lumen, and it is also the most mobile portion because it is suspended by the transverse mesocolon. That wide diameter is what the statement is conveying, and it helps explain why this segment is noted as the largest/widest in some anatomy descriptions. In ostomy practice, the sigmoid colon is the most common site for a colostomy because it is relatively fixed and easier to manage, but the transverse colon can be used for a stoma in specific situations if the sigmoid isn’t suitable. The other statements are incorrect because urine is stored by the bladder, and the transverse colon does have a role in ostomies in certain cases.
