lesser omentum
a double layer of peritoneum extending from the liver to the lesser curvature of the stomach
peritoneum
a smooth membrane that lines the entire abdominal cavity
ascites
accumulation of serous fluid in peritoneal cavity
inferiorly, posteriorly
ascites displaces the distended bladder _____ by not ______
greater omenuntum
attached to the greater curvature of the stomach and hangs down like an apron in the space between the small intestine and the anterior abdominal wall. it is able to adhere to diseased organs which helps prevent the spread of fluid
coronary ligament
attaches liver to diaphragm
subphrenic
below the diaphragm
hemorrhage
collection of blood
visceral peritoneum
covers the organs
lesser sac
extensive peritoneal pouch located behind the lesser omentum and stomach; extends upward to the diaphragm and inferior between the layers of the greater omentum.
lowest
fluid will accumulate in the _____ (most dependent) parts of the body
Splenorenal ligament
formed by the posterior reflection of the peritoneum of the spleen and passes inferiorly to overlie the left kidney. Forms the posterior portion of the left lateral border of the lesser sac. Separates the lesser sac from the renosplenic recess
greater sac of the peritoneum
general peritoneal cavity is known as the
inferior, posterior
hepatic and subhepatic lesions displace echoes ______ and ______
leukocytosis
increase in the number of leukocytes (white blood cells)
septicemia
infection in the blood
subhepatic
inferior to the liver
peritonitis
inflammation of the peritoneum
lesser sac
left margin is formed by the spleen and ligaments. the right margin opens into the greater sac through the epiplotic foramen. the caudate love of the liver is also considered a ______ structure
omental bursa
lesser sac is aka
anterior, posterior
lesser sac lies _____ to the pancreas and ______ to the stomach
parietal peritoneum
lines the walls
abscess
localized collection of pus
mesentery
loops of the digestive tract are anchored to the posterior wall of the abdominal cavity by this large double fold of peritoneal tissue
anterior, anterior
mass is confirmed to be in the retroperitoneal cavity when _______ or _____ displacement of the dilated ureters can be documented
gutters
most dependent areas in the flanks of the abdomen and pelvis where fluid may accumulate
gutters
pelvis and lateral flanks (_____) should be examined for pathologic collections of fluid
omentum
pouchlike extension of the visceral peritoneum from the lower edge of the stomach, part of the duodenum, and the transverse colon
coronary ligament
prevents collections in the right posterior subphrenic space from extending between the bare area of the liver and the diaphragm
greater sac
primary compartment; extends across the anterior abdomen and from the diaphragm to the pelvis
pyogenic
pus producing
ventrally, cranially
retroperitoneal lesions displace echoes _____ and _____
sandwich sign
sonographic sign that you see when a vessel or organ is surrounded by a tumor on either side
morison's pouch
space anterior to the right kidney and posterior to the inferior border of the liver
Morison's pouch
space anterior to the right kidney and posterior to the inferior border of the liver where ascites or fluid may accumulate or an abscess may develop
sepsis
spread of an infection from its initial site to the bloodstream
gastrosplenic ligament
the left lateral extension of the greater omentum that connects the greater curvature of the stomach to the superior splenic hilum and forms a portion of the left lateral border of the lesser sac
mesentery
the small intesting, transverse colon and sigmoid colon are suspended from the posterior abdominal wall by the ______
