Anatomy of the Liver Flashcards
What is the largest organ in the abdominal cavity, and where is it located?
- liver
- upper right (mainly) and left quadrant
What are some of the basic functions of the liver?
- digestion
- metabolism
- detoxification
- bile production
- glycogen storage
How many regions are in the abdomainl cacvity?
- 9
What are the upper 3 regions of the abdomen called fro right to left?
1 - right hypochondriac region
2 - epigastric region
3 - left hypochondriac region

What are the middle 3 regions of the abdomen called fro right to left?
1 - right lumbar region
2 - umbilical region
3 - left lumbar region

What are the lower 3 regions of the 9 regions of the abdomen called from right to left?
1 - right inguinal region
2 - hypogastric region
3 - left inguinal region

What does topography mean?
- study of an organ based on regions
- emphasises the relationships between organs and tissues

How many main lobes does the liver have?
- 2
- left and right (right is bigger)

What are the superior and inferior borders or the liver called?
- superior = diaphragmatic surface
- inferior = visceral surface
What are the 2 accessory lobes of the liver called?
1 - quadrate
2 - caudate

What is the large white struction on the anterior section of the liver and what role does it have in providing stability to the livers anatomical position?
- falciform
- attaches liver to anterior wall of abdomianl cavity

What is the falciform on the anterior aspect of the liver formed from?
- a fold from the peritoneum
The ligamentum teres (round ligament) is an attachment to the falciform ligament on the anterior section of the liver. What is this a remnant of?
- umbilical cord

What is the liver covered with?
- capsule
- peritoneum
What is the hilum of the liver called?
- porta hepatis

What passes through the hilium of the liver called the portal hepatis?
- portal vein
- hepatic artery proper
- common hepatic duct
- nerves and lymphatics

The falicorm opens up and covers the liver and then reflects onto the under surface of the liver forming triangle ligaments areas on the left and right side of the liver. How do these triangular ligaments provide structure to the liver?
- anchor the superior aspects of the liver to the diaphragm

The falicorm opens up and covers the liver and then reflects onto the under surface of the liver forming the lesser omentum. What is the lesser omentum?
- double fold of peirtoneum
- attaches the liver to the stomach and duodenum

The coronary ligaments (anterior & posterior layers) are formed from the triangula ligaments as the peritoneal folds over the liver. What do the coronary ligaments attach to, to help provide support to the liver?
- attaches the superior surface of the liver to the inferior surface of the diaphragm

What is bile, and what produces bile?
- dark-green-to-yellowish-brown fluid
- produced by the liver
- stored in the gall bladder

Once the hepatocytes have created the bile, how does it make its way into the gall bladder?
- bile canaliculi join to form left and right hepatic ducts
- left and right hepatic ducts converge into common hepatic duct
- common hepatic duct merges with cystic duct
- cystic duct merges with common bile duct

The common bile ducts connects the gall bladder, which can then connect to what providing bile to the GIT?
- duodenum

How much of the blood in the liver is in the arterial and venous blood vessels?
- arterial = 25%
- venous = 75%
The liver is located in the foregut, what are the main artery and veins supplying the foregut?
- coeliac artery
- portal vein
