The liver is the largest gland in the body and, after the skin, the largest single organ
It weighs approximately 1500 g
It occupies almost all of the right hypochondrium, epigastrium and left hypochondrium
The diaphragmatic surface of the liver is covered with visceral peritoneum, except posteriorly in the bare area of the liver where it lies in direct contact with the diaphragm.
In the third part of its course, it lies in a groove on the posterior surface of the head of the pancreas . Here, the bile duct comes into contact with the main pancreatic duct.
It is usually joined by the main pancreatic duct, and together they open into a small ampulla in the duodenal wall, called the hepatopancreatic ampulla (ampulla of Vater).
Acute cholecystitis is a sudden inflammation of the gallbladder that causes severeabdominal pain.
Acute cholecystitis produces discomfort in the right upper quadrant or epigastrium. Inflammation of the gallbladder may cause irritation of the subdiaphragmatic parietal peritoneum, which is supplied in part by the phrenic nerve (C3, 4, and 5). This may give rise to referred pain over the shoulder, because the skin in this area is supplied by the supraclavicular nerves (C3 and 4).
Boas' or Boas's sign is hyperaesthesia below the right scapula can be a symptom in acutecholecystitis (inflammation of the gallbladder)
