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 a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein.
The hepatocyte is a cell in the body that manufactures serum albumin, fibrinogen, and the prothrombin group of clotting factors (except for Factors 3 and 4). It is the main site for the synthesis of lipoproteins, ceruloplasmin, transferrin, complement, and glycoproteins. Hepatocytes manufacture their own structural proteins and intracellular ...
Hepatocytes constitute about 80% of the cell population of the liver, with the other 20% being occupied by Kupffer cells, hepatic stellate cells, endothelial cells and mesothelial cells, which are not exactly characteristic of the liver, but are present in the liver samples. [2] Histologically speaking, hepatocytes have specific characteristics.
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.
Regarding ideal numbers, the famous M.D. says: "Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80."
It is increasingly accepted that LSECs and Kupffer cells play complementary roles in the hepatic blood clearance process, referred to as the dual cell principle of waste clearance (6): LSECs clear macromolecules and nanoparticles roughly <200 nm by clathrin-mediated endocytosis whereas Kupffer cells clear larger particles >200 nm by phagocytosis.
For years, the upper limit of normal blood pressure (BP) for all adults was 140 systolic pressure (SBP) over 90 diastolic pressure (DBP) mmHg. Higher numbers usually required treatment .
Its normal blood volume, including both that in the hepatic veins and that in the hepatic sinuses, is about 450 milliliters, or almost 10 percent of the body's total blood volume. When high pressure in the right atrium causes backpressure in the liver, the liver expands, and 0.5 to 1 liter of extra blood is occasionally stored in the hepatic ...
