A human liver normally weighs approximately 1.5 kilograms (3.3 pounds) [11] and has a width of about 15 centimetres (6 inches). [12] There is considerable size variation between individuals, with the standard reference range for men being 970–1,860 grams (2.14–4.10 lb) [13] and for women 600–1,770 g (1.32–3.90 lb). [14]
For these purposes, hepatocytes are usually isolated from animal or human [8] whole liver or liver tissue by collagenase digestion, which is a two-step process. In the first step, the liver is placed in an isotonic solution, in which calcium is removed to disrupt cell-cell tight junctions by the use of a calcium chelating agent.
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 human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
BSc meteorologist Janice Davila tells Bored Panda that one of the most unknown facts from her field of expertise is that weather radars are slightly tilted upward in a half-degree (1/2°) angle.
The liver detoxifies and breaks down chemicals, poisons and other toxins that enter the body. For example, the liver transforms ammonia (which is poisonous) into urea in fish, amphibians and mammals, and into uric acid in birds and reptiles. Urea is filtered by the kidney into urine or through the gills in fish and tadpoles. Uric acid is paste ...
Bile (from Latin bilis), or gall, is a yellow-green/misty green fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine. In humans, bile is primarily composed of water, is produced continuously by the liver, and is stored and concentrated in the gallbladder.
