Intestine
Basic Anatomy and Physiology
The intestines are a portion of the alimentary tract extending from the pylorus to the anus. In mammals, the intestines are divided into two main segments: the small intestine and the large intestine. The small intestine consists of the duodenum, jejunum and ileum and the large intestine consists of the caecum and colon (Dyce, 2002). talk about anatomical and functional discreteness between the two.
