The following diagram illustrates the anatomy of the Small Intestine. In the small Intestine labeled diagram, we have shown the Large Intestine (Colon), Stomach, and Small Intestine (Duodenum, Jejunum, and Ileum). It should be noted here that a label diagram is a part of a diagram where you sometimes label anything by an arrow or line connecting the part of the diagram to the word being used as a label.
