Liver, Pancreas, and abdominopelvic cavity Flashcards
ALF of Liver
Appearance - reddish brow wedge shape vital gland
Location - inferiorly to diaphragm, upper right quadrant of abdomen
Function - It is a digestive gland which produces enzymes to break down various products. e.gProduces bile
Where is the liver connected
Connected to the hepatic portal vein and hepatic artery
Regions of liver
- right lobe
- left lobe
- quadrate lobe
- caudate lobe
What are the lobules
- functional units of liver
- comprised of millions of hepatic cells
what are lobules held together by
fine dense irregular connective tissue layer
what is the livers surface covered in
A serus coat from peritoneum
what separates the regions of liver
falciform ligament
ALF of gallbladder
Appearance- grey-blue hollow tapered sac
Location- in a shallow depression under right lobe of the liver
Function- storage of bile
size and volume of gallbladder
size - 7-10cm in length, 4cm in diameter
volume- ~50ml
ALF of pancreas
Appearance- light tan/pink flat pear shape
Location- sits right behind stomach, upper left of abdomen
Function- creates insulin, is digestive and endocrine
length of pancreas
~15cm
Ducts of pancreas
- main pancreatic duct
- accessory pancreatic duct
Where does the pancreas drain enzymes
through the duodenal papilla into duodenum
What does the abdominopelvic cavity contain
stomach liver pancreas spleen gallbladder kidneys small and large intestine urinary bladder reproductive organs
what is the peritoneum
A serous membrane which lines abdominal cavity, it supports many abdominal organs and a conduit for blood and lymphatic vessels and nerves
how many layers does the peritoneum have
2: mesothelial, connective tissue
Location of intraperitoneal space
within abdominal cavity
what does the intraperitoneal space contain
stomach and instines
what is the retroperitoneal
the structures behind the intraperitoneal space - kidneys, major vessels
What is the peritoneal membrane formed by
Two layers of peritoneum and the potential space between
Outer and inner layer of peritoneal membrane
Outer- parietal peritoneum
Inner- visceral peritoneum
What is a mesentery and what is it attached to
A double layer of visceral peritoneum which is attached to the gastrointestinal tract
What does a mesentery contain
blood vessels, nerves and other structures between layers
what is the peritoneal cavity
the space between mesenteric layers
what is the peritoneal cavity filled with
~50ml serous fluid
can peritoneal cavity layers slide over each other
yes
ALF of greater omentum
Appearance- large, apron like fold
Location- hanging down infront of the stomach
Function-prevents the parietal and visceral peritoneum of the abdominal cavity from adhering to each other
what is the greater omentum consisted of
double sheet of peritoneum folded on itself therefore, 4 layers
is the greater omentum in front of the small intestines and pelvis
small intestines - yes
pelvis- sometimes
how far can the greater omentum ascend to
it can ascend as far as the transverse colon
ALF of lesser omentum
Appearance - apron like
Location - extends from liver to lesser curvature of stomach and first part of duodenum
Function - separates the greater sac from the omental bursa
how many layers does the lesser omentum have
4 - it is also a double layer of peritoneum
Function of peritoneum
- reduce friction against other organs
- folds on itself to form falciform ligament
