The term 'bowel' is a general term used to refer to the digestive organs in the human body. Specifically, it refers to the small and large INTESTINE, also known as the GUT or INTESTINE. The small INTESTINE is composed of three sections: the duodenum, jejunum, and ileum. The large INTESTINE is composed of the cecum, colon, and rectum. The term 'bowel' can also be used to refer to the contents of the intestines, which are composed of partially digested food, bacteria, and other substances.
