What skeletal structure covers the liver?

A
  • the lower rib cage
96
Q

When the falciform ligament ascends to the superior portion of the liver it divides what is it called once it divides?

A

-The coronary ligament, and it forms a reflection that is continuous with the inferior side of the diaphragm.

97
Q

A
  • the hepatoduodenal ligament
101
Q

What is the route of metastasis from the abdomen to the thorax through the diaphragm?

A

-when the bare area of the liver becomes retroperitoneal it opens the lymph drainage through the diaphragm

102
Q

What is the function of the portal vein?

A
  • it dumps blood from the gut in the liver to be detoxified
103
Q
  • True or false venous drainage occurs through the porta hepatis?
A
  • False it occurs through the hepatic vein to the IVC just below the diaphragm
104
Q

Which artery does the cystic artery branch off of?

A
  • off of the right hepatic artery
105
Q

Justify this statement: the right hepatic artery not only supplies the right lobe and the quadate and caudate lobes as well?

A

-The right hepatic artery only supplies the right lobe. Or the left hepatic artery supplies left, caudate, quadate lobes.

106
Q

What is the course of bile?

A

-Bile is produced in the liver then unused bile by the duodenum is stored in the gall bladder, then when needed it travels down the cystic duct, then to the common bile duct, and finally out to the duodenum through the sphincter of oddi, and the major papilla
