What is Gastro-Intestinal ?
- The gastrointestinal (GI) system is made up of the GI tract plus accessory organs. In essence, the GI tract is a long hollow tube that extends from your oral cavity where food enters your body, via the oesophagus, stomach, small intestine, large intestine, rectum, and finally to the anus where undigested food is expelled. The accessory organs include the salivary glands, pancreas and liver. These secrete important enzymes into the digestive tract. The gall bladder, which stores bile, is also considered part of the GI system..
