Quizplus · Accepted Answer

The first portion of the small intestines is the duodenum, which is responsible for receiving partially digested food from the stomach and mixing it with digestive enzymes from the pancreas and bile from the liver. The cecum is the beginning of the large intestine, while the jejunum and ileum are further down the small intestine. The appendix is a small, finger-like structure attached to the cecum, but it is not part of the small intestine.
