Which term refers to the sacs in the large intestine that permit expansion?

• A. Haustra
• B. Jejunum
• C. Plicae
• D. Rugae

Answer: (A)

In the large intestine, the wall forms sac-like pouches called haustra, created by the taeniae coli. These haustra provide expandable segments that allow the colon to distend as it fills with feces and to accommodate shifting content during absorption and motility. The other terms belong to different parts or functions: Jejunum and plicae refer to folds and features of the small intestine that increase surface area, while rugae are folds of the stomach lining that permit stomach expansion. Haustra are the sacs that specifically enable expansion in the large intestine.
