Lecture 9: Abdomino-Pelvic Cavity Flashcards
The abdominal & Pelvic Cavities are __________
continuous, theres no physical seperation
Abdomino-Pelvic cavity Quadrants
Left Upper
Right Upper
Left Lower
Right Lower
Abdomino-Pelvic Cavity Regions
Left hypochondric
epigastric
right hypochondric
left lumbar
umbilical
right lumbar
left iliac
pubic
right iliac
Accessory organs of the digestive system & function
liver
gallbladder
pancreas
secrete products that aid digestion in the gastrointestinal tract via the common bile duct & the pancreatic duct
the spleen is
NOT a digestive organ, its just anatomically close to the upper left quadrant
The esophagus travels
posteriorly through the diaphragm to join the stomach
The esophagus enters the stomach at the
Cardia
The omentum functions
- protective functions
- facilitates migration of immune cells into the peritoneal cavity
- walls off areas of inflammation
- used as a source of tissue for wound repair
Greater Omentum Position
- extends from the greater curvature of the stomach
- covers the SI
- attaches to the transverse colon
Lesser Omentum position
- extends from the lesser curvature of the stomach
- attaches to both the liver and duodenum
Peritoneum function
double walled sac that contains sereous fluid & covers the organs
Mesentery function
suspends the jejunum & ileum from the posterior abdominal wall
Retroperitoneal organs
SAD PUCKER
suprarenal gland
aorta
duodenum
pancrease
ureters
colon
kidneys
esophagus
rectum
Duodenum of the SI details
fixes, thick walled, immobile
Jejunum & Ileum of the SI details
- relatively fluid, motile, easy to move around
- attach to the mesentary
Parts of the Large Intestine
Ascending Colon
right colic flexture
Transverse Colon
left colic flexture
Descending Colon
Sigmoid Colon
Rectum
Anal Canal
Diverticula Definition
tiny pouches that form in the colon
The Liver: Falciform ligament function
seperates the right and left lobes
The Liver is supplied blood by the
hepatic artery
Portal Triad
- hepatic artery proper
- hepatic portal vein
- bile duct
The liver removes blood by the
hepatic veins into the IVC
The Liver ________ & the gallblader ________
the liver produces bile continuously & the gallbladder stores/secretes bile
Movement of Bile
- right and left hepatic ducts take bile from the liver
- bile travels through the common hepatic duct
- bile travels to the hepatopancreatic ampulla
- bile & pancreatic secretions enter the duodenum
If bile isnt neede in the duodenum, then
bile moves back up int the gallbladder
Gallstones definition
hard deposits in the gallbladder
The spleen details
- largest immunological organ
- contains a large resovoir of leukocytes
- recivers/filters blood for surveillance/extraction of old erthyrocytes
- highly variable in size and morphology
Spleen issues
vulnerable to rupture in blunt trauma because of its superficial positioning posterio-laterally
The spleen is supplied by the
splenic artery
The celiac trunk supplies the foregut via
- common hepatic artery
- splenic artery
- left gastric artery
The superior mesenteric artery
supplies the digestive tract from lower duodenum through 2/3’s of the transverse colon
The inferior mesenteric artery function
supplies the descending colon, sigmoid colon and rectum
