Liver cell. Coloured scanning electron micrograph of a single human liver cell also known as hepatocyte. Hepatocytes have a polyhedral shape, having five to twelve sides, with a diameter of about 12 to 25 micrometers. Hepatocytes perform a multitude of functions: they synthesise various plasma proteins including albumin and clotting factors, regulate the blood level of amino acids and secrete bile which carries away waste products from the liver and helps the breakdown of fats in the small intestine. Bile is drained away in the bile canaliculi (green) and is stored in the gall- bladder. Magnification: x1725 at 6x7cm size.
