Which of the following statements applies to the ileocecal sphincter?
A) Cecal distention enhances relaxation of this sphincter.
B) Closure of this sphincter inhibits absorption in the small intestine.
C) Peristaltic contractions reaching this sphincter cause it to relax.
D) This sphincter is usually relaxed.
E) This sphincter stays contracted.
Ileocecal Sphincter
Thickening of circular smooth muscle between the ileum and the cecum, forming the ileocecal valve.

Final Answer :
C

EThe ileocecal sphincter relaxes in response to peristaltic contractions reaching it from the ileum, allowing contents to pass into the cecum. It remains contracted most of the time to prevent backflow from the cecum into the ileum.
