Blockage of the ileocecal valve would prevent

A) pancreatic juice from entering the duodenum.
B) bile from entering the duodenum.
C) lymph from entering the jejunum.
D) chyme from entering the ileum.
E) chyme from entering the large intestine.

The ileocecal valve is located between the ileum (the last portion of the small intestine) and the cecum (the first part of the large intestine). Its primary function is to prevent the backflow of contents from the large intestine into the small intestine. Therefore, blockage of the ileocecal valve would prevent chyme (partially digested food) from moving from the ileum into the large intestine.
