The 6 Main functions of the LIVER!?

Question

This is for biology, grade 12 level. If you know plz help! =)

Answer 1

It plays a major role in metabolism and has a number of functions in the body including glycogen storage, plasma protein synthesis, and drug detoxification.

The various functions of the liver are carried out by the liver cells or hepatocytes.

The liver produces and excretes bile required for dissolving fats. Some of the bile drains directly into the duodenum, and some is stored in the gallbladder.
The liver performs several roles in carbohydrate metabolism:
Gluconeogenesis (the formation of glucose from certain amino acids, lactate or glycerol)
Glycogenolysis (the formation of glucose from glycogen) (muscle tissues can also do this)
Glycogenesis (the formation of glycogen from glucose)
The breakdown of insulin and other hormones
The liver is responsible for the mainstay of protein metabolism.
The liver also performs several roles in lipid metabolism:
Cholesterol synthesis
The production of triglycerides (fats).
The liver produces coagulation factors I (fibrinogen), II (prothrombin), V, VII, IX, X and XI, as well as protein C, protein S and antithrombin.
The liver breaks down hemoglobin, creating metabolites that are added to bile as pigment.
The liver breaks down toxic substances and most medicinal products in a process called drug metabolism. This sometimes results in toxication, when the metabolite is more toxic than its precursor.
The liver converts ammonia to urea.
The liver stores a multitude of substances, including glucose in the form of glycogen, vitamin B12, iron, and copper.
In the first trimester fetus, the liver is the main site of red blood cell production. By the 32nd week of gestation, the bone marrow has almost completely taken over that task.
The liver is responsible for immunological effects- the reticuloendothelial system of the liver contains many immunologically active cells, acting as a 'sieve' for antigens carried to it via the portal system.

Answer 2

Function Of The Liver

Answer 3

The liver is one of the largest organs in the body, yet it gets very little respect. The brain, heart, and lungs are always described as essential to the body’s health. Without the liver, though, the physical body could not operate.

In general, people do not think about their liver until it malfunctions. Rodney Dangerfield always says: “What does a guy have to do to get some respect around here?” This questions truly applies to the liver and its operations. Since none of its functions can be observed, as the heartbeat, pulse, or respiratory rate, the liver is the last thing people think of or value.

Yet the liver is the link between the digestive and the circulatory systems. Some of the most important functions of the liver follow.

• The liver secretes bile that aids in the digestion of our food; for without it digestion could not take place.

• The liver detoxifies the blood and stores glucose, (i.e., sugar) the chief source of energy for the body.

• The liver acts as storage for numerous vitamins and minerals.

• The liver makes various substances that aid in the clotting of blood.

• The liver regulates the body’s metabolism.

• Finally, the liver regenerates itself.
