The intestine is a tube shaped structure that is part of the digestive tract. The intestine stretches from an opening in the stomach to the anus and occupies most of the lower parts of the belly. Food passes through the intestine and digestion takes place. Digestion is a process in which food is broken down and is absorbed (along with water) into the bloodstream.
The intestine is divided into two main sections: the small intestine and the large intestine. The small intestine takes in all of the nutrients that the body needs. The large intestine absorbs moisture from the matter that is left, and excretes the waste from the anus as feces (poop). Excrete means to release from the body as waste.
Many people associate the colon with the intestines. The colon is the major part of the large intestine. The top end of the colon is attached to the cecum, which is the first part of the large intestine. The bottom end of the colon is attached to the rectum, which is the last part of the large intestine. The intestine can be seen in this picture. Intestine is also known as the bowel, bowels, gut, and intestinum. Intestinal means relating to the intestine. Intestine comes from the Latin word "intestinus" meaning "inner."
