Stomach. Coloured X-ray of a barium meal (blue,upper right) in a normal human stomach (blue and orange). The stomach is a curved,sac-like organ that receives food from the oesophagus (blue,upper centre). The oesophagus contracts in waves of muscular contraction called peristalsis to pass food into the stomach. The stomach aids the initial digestion of food and passes it on into the intestines (not seen). The backbone (pink) is seen running vertically down centre. A barium meal is a radio-opaque substance that is swallowed to allow X-ray examinations of the digestive tract | |
