Liver fluke is a collective name of a polyphyletic group of parasitic trematodes under the phylum Platyhelminthes. [1] They are principally parasites of the liver of various mammals, including humans. Capable of moving along the blood circulation, they can occur also in bile ducts, gallbladder, and liver parenchyma. In these organs, they ...
Bile is secreted by the liver into small ducts that join to form the common hepatic duct. [4] Between meals, secreted bile is stored in the gallbladder. [5] During a meal, the bile is secreted into the duodenum (part of the small intestine) to rid the body of waste stored in the bile as well as aid in the absorption of dietary fats and oils. [5]
The biliary tree (see below) is the whole network of various sized ducts branching through the liver.. The path is as follows: bile canaliculi → canals of Hering → interlobular bile ducts → intrahepatic bile ducts → left and right hepatic ducts merge to form → common hepatic duct exits liver and joins → cystic duct (from gall bladder) forming → common bile duct → joins with ...
Clonorchis sinensis, the Chinese liver fluke, is a liver fluke belonging to the class Trematoda, phylum Platyhelminthes. It infects fish-eating mammals, including humans. In humans, it infects the common bile duct and gall bladder, feeding on bile. It was discovered by British physician James McConnell at the Medical College Hospital in ...
At birth, the liver comprises roughly 4% of body weight and weighs on average about 120 g (4 oz). Over the course of further development, it will increase to 1.4–1.6 kg (3.1–3.5 lb) but will only take up 2.5–3.5% of body weight. [40] Hepatosomatic index (HSI) is the ratio of liver weight to body weight. [41]
It is formed by the union of the right hepatic duct (which drains bile from the right functional lobe of the liver) and the left hepatic duct (which drains bile from the left functional lobe of the liver). [3] The duct is about 3 cm long. [4] The common hepatic duct is about 6 mm in diameter in adults, with some variation. [5]
The falciform ligament, visible on the front of the liver, makes a superficial division of the right and left lobes of the liver. From the underside, the two additional lobes are located on the right lobe. [2] A line can be imagined running from the left of the vena cava and all the way forward to divide the liver and gallbladder into two ...
The bile duct is some 6–8 cm long, and normally up to 8 mm in diameter. [4]Its proximal supraduodenal part is situated within the free edge of the lesser omentum.Its middle retroduodenal part is oriented inferiorly and right-ward, and is situated posterior to the first part of the duodenum, and anterior to the inferior vena cava.
