What is the role of liver in lipid metabolism?
The liver is the central organ for fatty acid metabolism. Fatty acids accrue in liver by hepatocellular uptake from the plasma and by de novo biosynthesis. Fatty acids are eliminated by oxidation within the cell or by secretion into the plasma within triglyceride-rich very low density lipoproteins.
How does the liver work?
Your liver works around the clock to keep you healthy. Among its most important jobs are: 1 Producing important substances. Your liver continually produces bile. This is a chemical that helps turn fats into energy that your body uses. Bile is necessary for the digestive process. Your liver also creates albumin. This is a blood protein that helps carry hormones, drugs, and fatty acids throughout your body. Your liver also creates most of the substances that help your blood clot after injury. 2 Processing bilirubin. The liver helps your body get rid of bilirubin. This happens from the breakdown of your red blood cells. Too much bilirubin in your body can cause jaundice. This is a yellowing of the skin and eyes. 3 Removing waste products. When you take in a potentially toxic substance, like alcohol or medicine, your liver helps alter it and remove it from your body. 4 Controls immune responses. When bacteria, viruses, and other harmful organisms enter your body, your liver can find and destroy them. This is done by specialized cells in your liver. 5 Controlling glucose. The liver helps your body maintain a healthy level of blood sugar. Your liver supplies glucose to your blood when it’s needed. It also removes glucose from your blood when there’s too much.

Where is the liver located in the human body?
7197. Anatomical terminology. The liver is an organ only found in vertebrates which detoxifies various metabolites, synthesizes proteins and produces biochemicals necessary for digestion and growth. In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm.
What are the functions of the liver?
The liver performs several roles in carbohydrate metabolism: 1 The liver synthesizes and stores around 100g of glycogen via glycogenesis, the formation of glycogen from glucose. 2 When needed, the liver releases glucose into the blood by performing glycogenolysis, the breakdown of glycogen into glucose. 3 The liver is also responsible for gluconeogenesis, which is the synthesis of glucose from certain amino acids, lactate, or glycerol. Adipose and liver cells produce glycerol by breakdown of fat, which the liver uses for gluconeogenesis. 4 Liver also does glyconeogenesis which is synthesis of glycogen from lactic acid.
How many functional lobes are there in the liver?
The Couinaud classification divides the liver into eight functionally independent liver segments. Each segment has its own vascular inflow, outflow and biliary drainage. In the centre of each segment are branches of the portal vein, hepatic artery, and bile duct. In the periphery of each segment is vascular outflow through the hepatic veins. The classification system uses the vascular supply in the liver to separate the functional units (numbered I to VIII) with unit 1, the caudate lobe, receiving its supply from both the right and the left branches of the portal vein. It contains one or more hepatic veins which drain directly into the inferior vena cava. The remainder of the units (II to VIII) are numbered in a clockwise fashion:
What is the lobule made of?
Each lobule is made up of millions of hepatic cells (hepatocytes), which are the basic metabolic cells. The lobules are held together by a fine, dense, irregular, fibroelastic connective tissue layer extending from the fibrous capsule covering the entire liver known as Glisson's capsule.
Why is lymph in the liver?
Because the pores in the hepatic sinusoids are very permeable and allow ready passage of both fluid and proteins into the perisinusoidal space , the lymph draining from the liver usually has a protein concentration of about 6 g/dl, which is only slightly less than the protein concentration of plasma. Also, the high permeability of the liver sinusoid epithelium allows large quantities of lymph to form. Therefore, about half of all the lymph formed in the body under resting conditions arises in the liver.
What is the line between the liver and gallbladder called?
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 halves. This line is called Cantlie's line.
Why is the liver important?
The liver is a vital organ and supports almost every other organ in the body. Because of its strategic location and multidimensional functions, the liver is also prone to many diseases. The bare area of the liver is a site that is vulnerable to the passing of infection from the abdominal cavity to the thoracic cavity. Liver diseases may be diagnosed by liver function tests –blood tests that can identify various markers. For example, acute-phase reactants are produced by the liver in response to injury or inflammation.
What is the substance produced by the liver that breaks up fat particles that are stored in the gallbladder and?
A substance produced by the liver that breaks up fat particles that is stored in the gallbladder and sprayed into the small intestines onto chyme. This is not an enzyme. It does not chemically digest food. It does, however, physically break up large fat particles into smaller fat droplets. Bile mixes with the fats in food to form small fat droplets. The droplets can be chemically broken down by enzymes produced in the pancreas.

Overview
The liver is a major organ only found in vertebrates which performs many essential biological functions such as detoxification of the organism, and the synthesis of proteins and biochemicals necessary for digestion and growth. In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm. Its other roles in metabolism include the regulation of glycogen storage, decomposition of red blood cells, and the production of hormones.
Structure
The liver is a reddish-brown, wedge-shaped organ with two lobes of unequal size and shape. A human liver normally weighs approximately 1.5 kg (3.3 lb) and has a width of about 15 cm (6 in). There is considerable size variation between individuals, with the standard reference range for men being 970–1,860 g (2.14–4.10 lb) and for women 600–1,770 g (1.32–3.90 lb). It is both the heaviest internal organ and the largest gland in the human body. Located in the right upper quadr…
Development
Organogenesis, the development of the organs, takes place from the third to the eighth week during embryogenesis. The origins of the liver lie in both the ventral portion of the foregut endoderm (endoderm being one of the three embryonic germ layers) and the constituents of the adjacent septum transversum mesenchyme. In the human embryo, the hepatic diverticulum is the tube of endoderm that extends out from the foregut into the surrounding mesenchyme. The mes…
Functions
The various functions of the liver are carried out by the liver cells or hepatocytes. The liver is thought to be responsible for up to 500 separate functions, usually in combination with other systems and organs. Currently, no artificial organ or device is capable of reproducing all the functions of the liver. Some functions can be carried out by liver dialysis, an experimental treatment for liver failure. The liver also accounts for about 20% of resting total body oxygen con…

Society and culture
Some cultures regard the liver as the seat of the soul. In Greek mythology, the gods punished Prometheus for revealing fire to humans by chaining him to a rock where a vulture (or an eagle) would peck out his liver, which would regenerate overnight. (The liver is the only human internal organ that actually can regenerate itself to a significant extent.) Many ancient peoples of the Near East and Mediterranean areas practiced a type of divination called haruspicy or hepatomancy, whe…
Other animals
The liver is found in all vertebrates and is typically the largest internal organ. The internal structure of the liver is broadly similar in all vertebrates, though its form varies considerably in different species, and is largely determined by the shape and arrangement of the surrounding organs. Nonetheless, in most species it is divided into right and left lobes; exceptions to this general rule include snakes, where the shape of the body necessitates a simple cigar-like form.
