Quizplus · Accepted Answer

The top portion of the small intestine is called the duodenum. The ileum is further down the small intestine, after the jejunum. The anus and rectum are part of the large intestine, not the small intestine. The ileocecal valve is a muscular valve that connects the end of the small intestine (ileum) to the beginning of the large intestine (cecum).
