Large intestine. Coloured X-ray image of the human abdomen showing the large intestine (colon),after a barium enema. At centre are loops of the small intestine. These lead into the dilated colon,of which there are three regions. At left is the ascending region of the colon; at top,the transverse colon runs horizontally,leading to the descending colon (at right). At bottom centre is the rectum. The colon absorbs water and electro- lytes from digested food; periodic muscular contractions move the dehydrated contents (faeces) towards the rectum. A barium enema is a suspension of barium sulphate (which is opaque to X-rays) that is infused into the rectum | |
