Which movements are considered types of movement of the large intestine?

• A. Peristaltic movement
• B. Segmental movements
• C. Mass movement
• D. All of the above

Answer: (D)

The large intestine uses several motility patterns to mix, absorb water, and move contents toward the rectum. Segmental (haustral) movements create mixing by contracting circular muscle and forming haustra, which helps expose the contents to absorptive mucosa and slow transit for better water absorption. Peristaltic movements in the colon are slower, wave-like contractions that propel contents forward along the colon. Mass movements are powerful, long-lasting contractions that move feces over long distances toward the rectum, often occurring after meals due to the gastrocolic reflex.

All of these movement types occur in the large intestine, so the best choice is all of the above.
