The liver scratch test can be used when other exam techniques used to approximate liver size are ineffective or unavailable [2] and is thought to be most useful if the abdomen is distended, too tender for direct palpation, the abdominal muscles are too rigid, or the patient is obese. [3]
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue , consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein .

Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.
The LiMAx test is an innovative enzymatic liver function test. 13 C-methacetin, a selective metabolite of the liver specific cytochrome P450 1A2 is administered intravenously. Via the bloodstream the drug is transported to the liver and immediately metabolized to paracetamol and ultimately to 13 CO 2 (Fig. 1), which is in turn transported via ...
A liver sinusoid is a type of capillary known as a sinusoidal capillary, discontinuous capillary or sinusoid, that is similar to a fenestrated capillary, having discontinuous endothelium that serves as a location for mixing of the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein.
Liver cirrhosis can lead to increased intrahepatic vascular resistance and vasodilation of portal system arteries, both of which increase pressure in the portal vein. [4] Color Doppler Ultrasound is the most useful imaging tool used to identify aneurysms, thrombosis, and branching patterns of the portal venous system, and to determine if ...
The function and role of quiescent hepatic stellate cells is unclear. Recent evidence suggests a role as a liver-resident antigen-presenting cell, presenting lipid antigens to and stimulating proliferation of NKT cells. [7] When the liver is damaged, stellate cells can change into an activated state.
