Digestive Indetofication Flashcards
Visceral peritoneum
Covers the surface of most digestive organs
Parietal peritoneum
Membrane that lines the body wall
Peritoneal cavity
Slit like cavity between parietal and visceral peritoneums containing fluid and allows for organs to slide around some while digesting
Mesentery
Provide route for blood vessels, lymphatics, and nerves, holds organs in place and stores fat
Splanchnic circulation
Circulation of blood to intestinal organs. It increases after food has been eaten
Oral orifice
Anterior opening to oral cavity
Red margin
Area of lips that lacks keratin and appears translucent
Labial frenulum
Fold of skin that connect lips to gum(there are two: one superior, one inferior)
Palatoglossal arch
Anchors tongue to soft palate
Palatopharyngeal arch
Connects tongue to Oropharynx
Lingual frenulum
Anchors tongue to floor of oral cavity and limits posterior movement
Filiform papillae
Gives tongue rough surface to lick and move food
Fungiform, circumvallate, and foliate papillae
Papillae on tongue that house taste buds
Terminal sulcus
Groove that determines where the part of the tongue in the oral cavity ends
Parotid gland
Located anterior to the ear and produces saliva
Parotid duct
Carries saliva from gland to mouth. It runs parallel to zygomatic arch and empties saliva next to the right upper molar
Incisors
Front teeth
Canines
Rip and tear
Molars
Smash and grind
Esophageal hiatus
Location in the diaphragm where the esophagus passes
Cardiac orifice
Place where esophagus and stomach join
Cardiac sphincter
Clave that surrounds the cardiac orifice
Peritoneum
Extensive serous membrane in the abdominopelvic cavity
Rugae
Long horizontal folds in the side of the stomach
Stomach
Protein digestion
Bile duct and pancreatic duct
Located in the small intestine and deliver bike and pancreatic juice respectively
Hepatopancreatic ampulla
Opens into the duodenum via major duodenal papilla
Ileocecal valve
Junction of small and large intestine
Superior mesenteric artery feeds…
Small intestine
Where does most absorption occur in the small intestine?
The proximal part
Plicae circulares
Small intestine, amplify absorption
Where does most absorption occur?
Duodenum
Villi
Small intestine, absorb nutrients
Duodenal glands
Duodenum, secrete mucus
Falciform ligament
Mesenteric that separates left and right liver lobe and suspends the liver from diaphragm and abdominal wall
Round ligament/ ligamentum teres
Remains of umbilical vein
Porta hepatis
Place where hepatic portal vein and hepatic artery enter liver
Common hepatic duct
Duct that results from anastomoses of right and left hepatic ducts and delivers bile to duodenum
Cystic duct
Anastomoses with common hepatic duct to form bile duct. It drains the gall bladder
Gall bladder
Stores bile that isn’t needed immediately for digestion
Portal triad
Present in every corner of all liver lobules, it’s the collection of a hepatic portal artery, pesticides portal vein, and a bile duct
Pancreas
Produces enzymes that break downs variety of food types
Main pancreatic duct
Drain pancreatic juice into duodenum
Acini
Clusters of secretory cells located near the ducts of the pancreas
Teniae coli
Bands of muscle around large intestine
Haustra
Pocket like sacs caused be the teniae coli
Epiploic appendages
Fat filled pouches of visceral peritoneum significance is unknown
Cecum
Lies below ileocecal sphincter
Colon (ascending, transverse, and descending)
Major part of large intestine
Right colic/hepatic flexure
Location in colon where it turns right and becomes the transverse colon
Left colic/splenic flexure
Location in colon where it turns downwards and becomes the descending colon
Sigmoid colon
located in the pelvis
Mesocolons
Mesenteric sheets that anchor the transverse and sigmoid colon the the abdominal wall
Rectal valve
Three internal folds in the rectum that prevent feces from coming out with gas
Anal canal
Last part of large intestine
Internal anal sphincter
Involuntary sphincter in anus
External anal sphincter
Voluntary sphincter located in anus
