-Peritoneal cavity: potential space between the parietal peritoneum and thevisceral peritoneum-Mesentery proper: double layer that suspends the different layers of the smallintestine from the posterior part of the abdominal wall-Mesocolon: double layer that surrounds the transverse colon-Greater omentum: extends from stomach and creates curtain in front of abdominalcavity
-Lesser omentum: double layer of peritoneum around connection from liver tostomach-Falciform ligament: where visceraL peritoneum doubles up and attaches toanterior body wall holds liver up by attaching it to the anterior wall-Coronary ligament: where parietal peritoneum attaches or meets the diaphragmfrom the superior part of the liverTerminology Connections-If an abdominal organ has a mesentery (double-layer of peritoneum suspending theorgan from the posterior abdominal wall), then it has the following: (ex. stomach)-Visceral peritoneum: serous layer > same thing as Tunica serosa-Is intraperitoneal suspended by perotenal layer within the peritoneal cavity)-If an abdominal organ does NOT have a mesentery (double-layer of peritoneumsuspending the organ from the posterior abdominal wall), then it has the following: (ex.duodenum)-Tunica adventitia: no peritoneum suspending it-Is retroperitoneal (outside of the peritoneal cavity, behind the parietal peritoneum)StomachParts/RegionsEpithelium lining mucosa: simple columnar epitheliumTunica muscularisDigestionMechanical: 3 muscle layers churn to help mix enzymes into chymeChemicalGastric folds = Rugae; increases surface area inside for secretion of enzymesinvolved in chemical digestionHiatal hernia: part of stomach protrudes up into esophagusGastric pits, glands: no goblet cells; deep dives in epithelium that contains gastricglandsGastric Secretions (stomach lining)-in gastric pit (top to bottom of pit)-surface mucous cell: secretes alkaline fluid containing mucin; help create carperof alkaline mucin to help protect simple columnar epithelium-mucous neck cell: secretes acidic fluid contain mucin; mucus that has to hadwater added to it-parietal cell: secretes intrinsic factor and hydrochloric acid; denatures proteinsand makes pepsin and releases intrinsic factor for absorption of B12-chief cell: secretes pepsinogen and gastric lipase: inactive form of pepsin that isinvolved in digesting proteins until it meets parietal cell that-enteroendocrine cell: secretes gastrin into blood;Small IntestineThree segments; helps with chemical digestion and absorptionDuodenum: forms first part of small intestine and originates at the pyloricsphincter
-circular folds that help slow down movement of materials travelingthrough so that that absorption can take place-major duodenal papilla: opening that receives secretions from gallbladderin liver fro common bile duct and pancreatic ductJejunum: primary region for chemical digestion and absorption; contains circularfoldsIleum: directly connected to large intestine by the cecum by the ileocecal valve;longest region; contains circular fold
