The Colon (large intestine or bowel) is a muscular tube approximately 1.5 to 2 metres (5 to 7.5 feet) in length and has an average diameter of 9cm (3.5 inches). The small intestine empties its waste products from the foods eaten into the caecum, the first section of the colon, via the ileo-caecal valve.

The Colon begins on the lower right side of the abdomen and travels up as the ascending colon; near the ribs it bends sharply to the left and crosses the abdomen as the transverse colon, which ultimately empties waste into the rectum, to then be eliminated from the body via the anus. The muscular contraction that enables this to happen is called peristalsis.
 
The following chart illustrates the importance of how health and sickness have their roots in the colon. It is easy to see how an improper diet affects your colon and, in turn, inflicts pain or discomfort on other parts of the body. The colon outline is that which would appear in the X-ray of a truly healthy colon.

The five pictures below of prolapsed, distorted, twisted, sickly looking colons are exact reproductions of X-ray negatives of the colons of apparently healthy civilized people whose illusions about their physical condition were exploded when they saw this conclusive evidence.

Civilized life means an artificial life; civilized people, living in a civilized manner and eating civilized foods, cannot, in the very nature of things, have a truly healthy colon.
