Gastrointestinal (GI) & Genitourinary (GU) Procedures The gastrointestinal tract (GI tract) houses many important organs that play an essential role in the digestion of food. These organs include the mouth, esophagus, liver, stomach, gallbladder, pancreas, small intestine, and large intestine. The rectum and anus, located within the large intestine, are included in the GI tract. The genitourinary tract (GU tract) is comprised of the urinary and reproductive organs. These organs include the kidneys, adrenal glands, ureters, urinary bladder, urethra, and male reproductive organs (testes, epididymis, vas deferens, seminal vesicles, prostate gland, and penis).
