The ileocecal sphincter is located between the ileum (last part of the small intestine) and the cecum (first part of the large intestine). When the ileum is distended with contents, the stretch receptors in the wall of the ileum signal the smooth muscle of the ileocecal sphincter to relax, allowing the contents to pass into the cecum.
