The abdomen

   The main organs of the body have ordinary English names and doctors use these words. But when an adjective is needed they often use an anatomical word. For exemple, we can say disease of the liver or hepatic disease. Some abdominal organs, for exemple the pancreas, have no ordinary name.

      When doctors talk about the main parts of the digestive system, they use the word bowel or intestine: the small intestine   or the small bowe, the large intestine or the large bowel.

When speaking to patients, doctors may refer to the anus and rectum as the back passage.

     The chest, contains the organs  of respirations and the heart. The main parts of the respiratory system are the airways and the lungs. The left lung is devidid into two lobes, and the right into three. The airways consist of the larynx, the trachea, the right and left bronchus, and the bronchioles. The chest is separated  from the abdomen by the diaphragm.
