Gastrointestinal Tract Anatomy Matching Exercise

Transverse colon = Travels horizontally across the abdomen and bends to form the descending colon Peristalsis = Rhythmic dilation and contraction of the gastrointestinal tract as food is propelled through it Gastrin = Endocrine hormone released from the stomach; stimulates secretion of gastric acid Meckel’s point = Congenital sac or blind pouch found in the lower portion of the ileum

Abscess = Localized collection of pus surrounded by inflamed tissue Cholecystokinin = Hormone secreted into the blood by the mucosa of the upper small intestine; stimulates contraction of the gallbladder and pancreatic secretion of enzymes McBurney’s point = Located by drawing a line from the right anterosuperior iliac spine to the umbilicus; at approximately the midpoint of this line lies the root of the appendix Secretin = Released from small bowel as antacid; stimulates secretion of bicarbonate

Appendicolith = Calcified deposit within the appendix; appendicitis can develop when the appendix becomes blocked by hard fecal matter Diverticulum = Pouchlike herniation through the muscular wall of a tubular organ that occurs in the stomach, the small intestine or, most commonly, the colon Hemorrhage = Collection of blood Target sign = Characteristic of gastrointestinal wall thickening consisting of an echogenic center and a hypoechoic rim

<p>alimentary canal = Also known as the digestive tract; includes the mouth, pharynx, esophagus, stomach, duodenum, and small and large intestine cardiac orifice = Entrance of the esophagus into the stomach greater omentum = Double fold of the peritoneum attached to the duodenum, stomach, and large intestine; helps support the greater curvature of the stomach; known as the &quot;fatty apron&quot; mesentery = Fold from the parietal peritoneum that attaches to the small intestine, anchoring it to the posterior abdominal wall</p> Signup and view all the answers

<p>gastrophrenic, gastrosplenic, and lienorenal ligaments = Help support the greater curvature of the stomach hepatic flexure = Ascending colon arises from the right lower quadrant to bend at this point to form the transverse colon mucosa = First layer of bowel pyloric canal = Helps support the lesser curvature of the stomach</p> Signup and view all the answers
