Liver

it filters out impurities from the body like alcohol and tobacco

The liver has over 500 functions

Some of the main ones include

• The processing of digested food from the intestine
• Controlling blood levels of amino acids, glucose and fats
• Fighting infections in the body
• Converting glucose to glycogen
• Cleansing particles, infections and bacteria from the blood
• Destroying, neutralizing & filtering harmful substances from the blood
• Manufacturing bile
• Storing minerals, vitamins (B12, A, D & K)
• Producing cholesterol
• Breaking down food and converting it into energy
• The manufacture of, breaking down and regulating of many hormones
• The making of proteins & enzymes for the majority of chemical reactions in the body
• Producing urea
• Producing substances that break down fats
• Maintaining a healthy level of glucose in the blood

To detox the body.

Your liver removes all toxins from your blood. It's like your bodies very own filter from all things that your body can't process on its own.

The liver has several functions. some include detoxification (getting toxins out), synthesizing proteins and producing acids such as gastric acids necessary for digestion.

Functions of liver:

1. Converts toxic product into nontoxic ones.

2. Liver actively participates in metabolism of Carbohydrates, Fats, Proteins, Vitamins and Minerals.

3. It excretes bile pigments, bile salts, cholesterol through bile.

4. It synthesizes plasma proteins.

5. It stores glycogen, vitamin A, D and B12 and trace elements.

And thats all the functions that the liver is mostly used for

When the blood glucose concentration becomes excessive; liver converts the glucose into glycogen. Liver converts the glycogen back to the glucose when energy is needed.

2: Metabolism

Liver is responsible for the metabolism of proteins and fats. It synthesizes blood clotting factors and stores various types of vitamins.

3:Bile secretion

The hypatocystes (cells) of liver secrete bile. The bile is stored in gallbladder.The bile duct of liver and cystic duct of gallbladder form common bile duct. The common bile duct join the pancreatic duct, the bile from common bile duct and pancreatic juice from pancreatic duct empty into duodenum (of small intestine) through the sphincter of oddi (valve) if it is opened. The opening of this valve is controlled by a hormone called Cholecystokinin.

Bile juice helps in emulsificaton of fats.

Bile is alkaline solution. Its molecules have dual nature (one end is attracted to water molecule while other is attracted to fat molecule). Thus its molecules remain in between water molecules and fat molecules (emulsification process).

If bile molecules were not present between fats and water, the fat molecules would be repelled by water molecules and be attracted to each other. The fat molecules would merge together because fats are insoluble in water. The merged fats would not be easily broken down with lipase (fat digesting enzyme).

4:Breakdown of old red blood cells

Liver breaks down the old red blood cells into bilurubin. Bilurubin is excreted in bile and urine.

5: Detoxification

Liver contains macrophages called Kupffer cells. These cells engulf and breakdown toxic matter such as microorganisms, dead cells and chemicals. Kupffer cells ingest microorganism by phagocytosis. The engulfed microorganism is called phagosome. Lysosmes in the cytoplasm of kupffer cell, fuse with the phagosome and release digestive enzymes. These enzymes breakdown and kill the microorganism.

But how does kupffer cell identify toxic matter?

There are receptors for the toxic matter on the surface of kupffer cells. The harmful particle and these receptors of kupffer cell can fit together like pieces of a puzzle. The harmful particle is then engulfed by kupffer cell.
remove toxins ingested in food.
It's the great chemist, changing the stuff you eat into the chemicals you need to live.

It also dumps a fair amount of waste (bile salts) and converts a number of poisons into water soluble salts (to be removed by the kidneys).

The Liver has a number of functions in the body, including glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification. The liver is necessary for survival; there is currently no way to compensate for the absence of liver function.

The liver is necessary for survival; there is currently no way to compensate for the absence of liver function. liver is responsible for making bile . Bile is a greenish bitter digestive liquid that contains bile salts and bile pigments. Bile salts consist of death enthrocytes, RBC's- Biliverdin and Bilirubin. Bile pigments are responsible for the emulsification of fats.
The liver has several functions critical to life. The liver takes all the toxic out of body. It also makes glucose.
