abdominal organs Flashcards
abdominal viscera
- stomach
- intestines
- spleen
- pancreas
- liver
- gallbladder
- kidneys
what surrounds all the organs/viscera
visceral peritoneum
what surrounds the inner abdominal walls
parietal peritoneum
what is the space between the parietal and visceral layers
peritoneal cavity
what is continuous with the posterior part of the peritoneum
mesentery
chief function of the stomach
enzymatic digestion
4 parts of the stomach
cardiac, fundus, body, pyloric
what are the ridges in the wall of the stomach called
rugae
function of rugae
increase extensibility and SA
the duodenum wraps around what
head of the pancreas
4 parts of the duodenum
- superior
- descending
- horizontal
- ascending
where do the common bile duct and pancreatic duct empty into
descending portion of the duodenum
parts of the large intestine
- cecum
- appendix
- ascending colon
- transverse colon
- descending colon
- sigmoid colon
- rectum
- anal canal
three longitudinal bands of smooth muscle in L intestine
teniae coli
pouches or sacculations on L intestine
haustra
fat filled bags on large intestine
epiploic appendices
omentum
double layer of peritoneum linking two adjacent organs
- immune functions
- where you gain fat
number of layers of greater omentum
4 (2 double layers)
the omentumms come from what layer of peritoneum
visceral
greater omentum joins
greater curvature of stomach to superior transverse colon
lesser omentum joins
superior stomach to inferior liver
rectum is at the level of
pelvic diaphragm
rectum and anal are at __ degrees
90
internal sphincter ani
involuntary (parasymp)
external sphincter ani
voluntary (postpone defecation)
-changes angle of anal canal
what m forms the external sphincter ani
levator ani
some functions of liver
- store glycogen
- metabolism
- secretes bile
right lobe landmarks
to the right of IVC and gallbladder
left lobe landmarks
left of ligaments
two surfaces of the liver
- diaphragmatic
- visceral
what ligament passes between the right and left lobes of liver
falciform ligament
ligaments of the liver
- coronary
- falciform
- teres
- venosum
what ligament is next to the IVC
venosum
what ligament is next to gall bladder
teres
what connects the ligamentum teres and venosum with the IVC and gallbladder
porta hepatis (hepatic a, portal v, common bile duct)
how many lobes of liver
4 (right, left, caudate, quadrate)
what lobe is between teres and gall bladder
quadrate
what lobe is between venosum and iVC
caudate
portal vein drains blood from
GI and spleen and brings it to liver
what veins make up portal vein
splenic and superior mesenteric
where does the portal vein travel in
lesser omenum
what duct leaves the gall bladder
cystic duct
cystic duct combines with what to form what
cystic duct combines with common hepatic duct to form the bile duct
exocrine function of pancreas
produce digestive enzymes
endocrine function of pancreas
islet of langerhands produce insulin
largest lymph organ
spleen
4 features of spleen
- diaphragmatic surface
- visceral surface
- notched anterior border
- hilus
tail of pancreas touches
tip of spleen on visceral surface
function of spleen
- produce lymphocytes
- storehouse for blood
- filters debris
- breaks down worn out RBC
level of vertebra of kidney location
T12 to L3
what is found between renal pyramids
renal columns
path in the kidney
renal pyramid => minor calyces => major calyces => renal pelvis => ureter
between which two lobes is the teres ligament found
between left lobe and quadrate
between which two lobes is the venous ligament found
between left lobe and caudate
