Appears as bright echogenic foci on transverse image; along with falciform ligament, it divides medial and lateral segments of the left lobe of the liver
Ligamentum teres
Uncontrolled increase in blood glucose level
Hyperglycemia
Yellow pigment in bile formed by the breakdown of red blood cells; excreted by the liver and stored in the gallbladder
Bilirubin
Tumor that develops away from the site of the organ; most common form of neoplasm of the liver; primary sites are the colon, breast, and lung
Metastatic disease
Vein formed by union of the splenic vein and superior mesenteric vein; serves as the posterior border of the pancreas; enters the liver at the porta hepatis
Main portal vein
Area superior to the liver that is not covered by peritoneum so that the inferior vena cava may enter the chest
Bare area
Affects hepatocytes and interferes with liver function
Diffuse hepatocellular disease
Extends from the umbilicus to the diaphragm in a sagittal plan and contains the ligamentum teres
Falciform ligament
Right upper quadrant of the abdomen that contains the liver and gallbladder
Right hypochondrium
Supplies the right lobe of the liver, branches into the anterior and posterior segments
Right portal vein
A parenchymal liver cell that performs all functions ascribed to the liver
Hepatocyte
Left upper quadrant of the abdomen that contains the left lobe of the liver, spleen, and stomach
Left hypochondrium
Largest lobe of liver
Right lobe
Any new growth
Neoplasm
Laboratory measurement of the amount of nitrogenous waste and creatinine in the blood; waste products accumulate in the blood when kidneys malfunction
Blood urea nitrogen
Specific laboratory tests that look at liver function
Liver function test
Hypoechoic mass with an echogenic central core
Bulls eye lesion
Lies in the epigastrium and left hypochondrium
Left lobe of liver
Flow away from the liver
Hepatofungal
Boundary between the right and left lobes of the liver; seen as a hyperechoic line on the sagittal image extending from the portal vein to the neck of the gallbladder
Main lobar fissure
Separates the left lobe from the caudate lobe; shown as an echogenic line on the transverse and sagittal images
Ligamentum Venosum
Flow toward the liver
Hepatopedal
Within the liver
intrahepatic
Area between the right and left hypochondrium that contains part of the liver, duodenum, and pancreas
