What are the parts of the liver?
The liver consists of four lobes: the larger right lobe and left lobe, and the smaller caudate lobe and quadrate lobe. The left and right lobe are divided by the falciform (“sickle-shaped” in Latin) ligament, which connects the liver to the abdominal wall.
What is Calot's triangle?
Calot described this triangle in 1891 formed by the cystic duct, hepatic duct, and the cystic artery. This triangle has now been modified to the cystohepatic triangle. In reality, it is a space bounded by the cystic duct, hepatic duct, and the inferior surface of the liver.
What are the landmarks of the liver?
They include the portal veins, hepatic veins, IVC, ligamentum teres, ligamentum venous, gallbladder, and right kidney. In the left lobe, the important landmarks are the left hepatic vein and middle hepatic vein, which separate S2 from S3 and S4 from the right anterior segments (S5 and S8), respectively.
Does the diaphragm cover the liver?
The liver is an organ located in the upper right part of the belly (abdomen). It is beneath the diaphragm and on top of the stomach, right kidney, and intestines.
What is costal surface in anatomy?
The costal surface is covered by the costal pleura and is along the sternum and ribs. It also joins the medial surface at the anterior and posterior borders and diaphragmatic surfaces at the inferior border. The medial surface is divided anteriorly and posteriorly.
Which of the following would not be lined by peritoneum?
The heart is not covered by visceral peritoneum.
What is the difference between peritoneal and visceral?
The main difference between visceral and parietal is that visceral is one of the two layers of the serous membrane, covering the organs, whereas parietal is the second layer of the serous membrane, lining the walls of the body cavity.
What is visceral and parietal peritoneum?
Parietal peritoneum – an outer layer which adheres to the anterior and posterior abdominal walls. Visceral peritoneum – an inner layer which lines the abdominal organs. It's made when parietal peritoneum reflects from the abdominal wall to the viscera.
Which fold of visceral peritoneum attaches the liver to the anterior abdominal wall?
b) The falciform ligament:– Attaches the liver to the anterior abdominal wall and diaphragm.
Which surface of the liver faces adjacent abdominal organs?
the posteroinferior surface of the liver that faces adjacent abdominal organs; the porta hepatis and gallbladder are located on this surface.
What is the posteroinferior surface of the liver?
the posteroinferior surface of the liver that faces adjacent abdominal organs; the porta hepatis and gallbladder are located on this surface. Synonym (s): facies visceralis hepatis [TA] Farlex Partner Medical Dictionary © Farlex 2012.
Where is the liver located?
Liver. The liver is a large essential organ found in the upper right quadrant of the abdomen. It is a multifunctional accessory to the gastrointestinal tract and performs such duties as detoxification, protein synthesis, biochemical production and nutrient storage to name but a few.
What is the liver covered by?
It works synchronously with many other organs and contributes to the maintenance of the basic homeostatic mechanisms. It is completely covered by visceral peritoneum, with the exception of the bare area, which is where the liver is in contact with the diaphragm. Key facts. Function.
What is the function of portal vein?
Vascularization. Functional: portal vein (metabolic processing of the matters absorbed in intestines) Nutritive: hepatic artery (supplying the tissue of the liver with oxygen and nutrients) Drainage: hepatic vein -> inferior vena cava -> right atrium. Innervation.
Why is the liver considered a special organ?
The liver is a special organ in the sense that it receives more venous blood than arterial blood and this is due to the fact that the liver helps clean the blood via detoxification. The majority of the vascular supply is brought into the organ by the portal vein which carries the blood filled with metabolytes absorbed in the intestines, whereas the rest of the blood comes from the common hepatic artery which originates from the celiac trunk and carries the oxygenated blood to the liver.
Why is the liver important?

What is the left triangular ligament?
Left triangular ligament - is a mix of the falciform ligament and the lesser omentum. Falciform ligament - is not of embryological origin, but a peritoneal reflection of the upper abdominal wall from the umbilicus to the liver and has the round ligament of the liver on its free edge.
Where does lymphatic drainage go?
The deep system consists of hepatic lymph vessels which follow the hepatic portal veins, therefore most of the lymph will flow towards the hepatic nodes at the hilum of the liver, which drain to the celiac nodes.
What are the two surfaces of the liver?

Where is the liver located?
The liver is an intraperitoneal organ found inferior to the diaphragm and deep to the 7th to 11th ribs. The location of the liver is such that you just can’t miss it, as it spans through three abdominal regions; right hypochondriac, epigastric and left hypochondriac.
What are the microscopic structures of the liver parenchyma?
The microscopic anatomy of the liver parenchyma is represented by the hepatic lobules. They consist of cords of hepatocytes surrounding a central vein . Sinusoids and portal triads are also part of the hepatic lobules.
Which duct is responsible for the flow of bile and pancreatic juice?
The common bile duct unites with the pancreatic duct to form the ampulla of Vater (hepatopancreatic ampulla), which opens into the duodenum on the major duodenal papilla. The flow of bile and pancreatic juice is controlled by the sphincter of Oddi. Anatomy of the biliary system and gallbladder location: Anterior view.
How many lobes does the liver have?
The liver has two surfaces; diaphragmatic and visceral. The surfaces show several fissures, which together with the ligaments divide the liver into four lobes: Left and right lobes, separated by the falciform ligament. Caudate and quadrate lobes, delimited by the fissures of the visceral surface.
Which ducts secrete bile?
Hepatocytes synthesize and secrete bile via the right and left hepatic ducts. These ducts fuse into a single common hepatic duct in the lateral part of the porta hepatis. The neck of the gallbladder funnels off into the short cystic duct. This duct combines with the common hepatic duct to form the common bile duct.
What veins are responsible for the venous drainage of the liver?
