Gastrointestinal Bleeding: Upper vs Lower GI Tract
Hemorrhage can originate from any region of the GI tract and is typically classified based on its location relative to the ligament of Treitz.
The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
