| jejunum | The section of the small intestine that comprises the first two fifths beyond the duodenum and that is larger, thicker-walled, and more vascular and has more circular folds than the ileum [Brenda]. | — |
| ileum | The last division of the small intestine extending between the jejunum and large intestine [Brenda]. | — |
| vermiform appendix | A narrow blind tube usually about three or four inches (7.6 to 10.2 centimeters) long that extends from the cecum in the lower right-hand part of the abdomen, has much lymphoid wall tissue, normally communicates with the cavity of the cecum, and represents an atrophied terminal part of the cecum [Brenda]. | — |
| large intestine | The more terminal division of the vertebrate intestine that is wider and shorter than the small intestine, typically divided into cecum, colon, and rectum, and concerned especially with the resorption of water and the formation of feces [Brenda]. | — |
| colorectal | Colorectal includes the colon and the rectum [MedTerms: http://www.medterms.com/script/main/art.asp?articlekey=2794]. | — |
| colon | The part of the large intestine that extends from the cecum to the rectum [Brenda]. | — |
| appendix | The appendix (or vermiform appendix; also cecal (or caecal) appendix; also vermix) is a blind-ended tube connected to the cecum (or caecum), from which it develops embryologically. The cecum is a pouchlike structure of the colon. The appendix is located near the junction of the small intestine and the large intestine. The term "vermiform" comes from Latin and means "worm-shaped". It is widely present in the Euarchontoglires and has also evolved independently in the diprotodont marsupials and is highly diverse in size and shape [Wikipedia: http://en.wikipedia.org/wiki/Vermiform_appendix]. | vermiform appendix; cecal appendix; caecal appendix; vermix |
| rectum | The terminal part of the intestine from the sigmoid flexure to the anus [Brenda]. | — |
| anus | The posterior opening of the alimentary canal [Brenda]. | — |
| mesentery | One or more vertebrate membranes that consist of a double fold of the peritoneum and invest the intestines and their appendages and connect them with the dorsal wall of the abdominal cavity [Brenda]. | — |
| omentum | A sheet of fat that is covered by peritoneum. The greater omentum is attached to the bottom edge of the stomach, and hangs down in front of the intestines. Its other edge is attached to the transverse colon. The lesser omentum is attached to the top edge of the stomach, and extends to the undersurface of the liver [Omentum: http://www.medterms.com/script/main/art.asp?articlekey=4632]. | — |
| greater omentum | The greater omentum (also the great omentum, omentum majus, gastrocolic omentum, epiploon, or, especially in animals, caul) is a large fold of visceral peritoneum that hangs down from the stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and reflects on itself to ascend to the transverse colon before reaching to the posterior abdominal wall. The common anatomical term "epiploic" derives from "epiploon" from the Greek "epipleein" meaning to float or sail on, since the greater omentum appears to float on the surface of the intestines [Wikipedia: http://en.wikipedia.org/wiki/Greater_omentum]. | — |
| lesser omentum | The lesser omentum (small omentum; gastrohepatic omentum; omentum minus) is the double layer of peritoneum that extends from the liver to the lesser curvature of the stomach and the start of the duodenum [Wikipedia: http://en.wikipedia.org/wiki/Lesser_omentum]. | — |
| peritoneum | The smooth transparent serous membrane that lines the cavity of the abdomen of a mammal and is folded inward over the abdominal and pelvic viscera [Brenda]. | — |
| liver and biliary system | The biliary system consists of the organs and ducts (bile ducts, gallbladder, and associated structures) that are involved in the production and transportation of bile [MedicalCenter: http://medicalcenter.osu.edu/patientcare/healthcare_services/liver_biliary_pancreatic_disease/biliary_system_anatomy/Pages/index.aspx]. | — |
| liver | 1: A large very vascular glandular organ of vertebrates that secretes bile and causes important changes in many of the substances contained in the blood (as by converting sugars into glycogen which it stores up until required and by forming urea).n2: Any of various large compound glands associated with the digestive tract of invertebrate animals and probably concerned with the secretion of digestive enzymes [Brenda]. | — |
| gall bladder | A small, pear-shaped muscular sac, located under the right lobe of the liver, in which bile secreted by the liver is stored until needed by the body for digestion [Brenda]. | — |
| bile duct | Any of the ducts that convey bile in and from the liver [Brenda]. | — |
| pancreas | A large lobulated gland of vertebrates that secretes digestive enzymes and the hormones insulin and glucagon [Brenda]. | — |
| exocrine pancreas | That part of the pancreas that acts as an exocrine gland, consisting of the pancreatic acini, which produce pancreatic juice and secrete it into the duodenum to aid in protein digestion [Brenda]. | — |
| urogenital system | The urinary system and genital system considered together [Brenda]. | — |
| urinary system | The organs and passageways concerned with the production and excretion of urine, including the kidneys, ureters, urinary bladder, and urethra [Brenda]. | — |
| kidney | 1: One of a pair of vertebrate organs situated in the body cavity near the spinal column that excrete waste products of metabolism, in humans are bean-shaped organs about 4 1/2 inches (11 1/2 centimeters) long lying behind the peritoneum in a mass of fatty tissue, and consist chiefly of nephrons by which urine is secreted, collected, and discharged into a main cavity whence it is conveyed by the ureter to the bladder.n2: Any of various excretory organs of invertebrate animals [Brenda]. | — |
| ureter | The tube that carries urine from the kidney to the bladder [Brenda]. | — |
| bladder | A membranous sac in animals that serves as the receptacle of a liquid or contains gas [Brenda]. | — |
