The liver is the largest internal organ in the body, excluding the skin. The adult liver weighs about 1.3 kg and contains about 13% of blood. This organ is cone-shaped and dark red-brown, located below the diaphragm and above the stomach. Find out what role the liver plays in the body.The article was consulted with Specialist Doctor I Vo Thi Thuy Trang - Department of Medical Examination & Internal Medicine - Vinmec Da Nang International General Hospital.
1. What role does the liver have?
The liver does three main jobs:
1.1. Liver Detox Most of the medications you take pass through the liver. In some cases, the organ has to secrete chemicals to "trigger" certain drugs to work. Liver chemicals also control the rate at which the drug is broken down, used, and then "neutralized" and excreted in the urine or feces.
It is the blood from your intestines that also carries toxins. Anything left over after the body uses it will be broken down by the liver to be excreted. Waste can move in the bile and pass out in the stool, or enter the bloodstream, then reach the kidneys and leave the body when you urinate. In addition to toxins in food, the liver also breaks down toxins found in alcohol, pesticides, and heavy metals, and turns them into harmless substances that are easily eliminated. Toxins can also be left over from normal body functions, such as hormone production.
1.2. Storing fuel The small intestine absorbs nutrients from food such as sugars, glycerol, amino acids, vitamins, minerals, and salts and transfers them to the bloodstream through special cells. The first stop is the liver, which converts nutrients into usable forms, then stores some, including iron, folate, and vitamins A, D and B12, to deliver them in the right places. when the body needs it.
Glucose or blood sugar is instant fuel for the body. The liver normally stores the energy you take in during the day in the form of glycogen. If you fast for a while and your blood sugar drops too low, the liver quickly converts glycogen back into glucose. This process can happen while you are sleeping.
In addition, the liver also helps to keep the balance of energy sources. This organ is not only an abundant source of fast fuel (glucose), but also takes amino acids from digested food and converts it into fatty acids. When you run out of glucose, the liver can change those fatty acids into another form of energy, called ketones. This process occurs in people following the keto diet.
1.3. Make bile to help digest food The liver uses cholesterol to make digestive juices, called bile. This fluid helps break down fats and certain vitamins for your body to use. Small bile ducts carry bile from the liver to the gallbladder, where it is stored and supplied to the small intestine when needed.

2. Other roles of the liver
In addition to the three main functions outlined above, this wonderful organ is involved in hundreds of other functions of the body. Which includes:
Supports the immune system Along with the ability to filter toxins, the liver can find, capture and destroy harmful bacteria, viruses and other germs that enter the body through the food. to drink. This organ has the largest pool of phagocytes to fight bacteria and is ready to launch a full-blown immune response when needed.
Sharp thinking The liver also helps you to be smarter and think more clearly by removing toxins from the blood. When liver function is affected, chemicals can build up and change your mood, sleep habits, and the way you act. You may feel depressed, anxious, or have trouble concentrating. Over time, you may also experience hand tremors, muscle twitching, and slurred speech. Scientists are still trying to figure out exactly what toxins lead to this condition.
Chemical Factory The liver uses nutrients to make hundreds of substances the body needs. The liver breaks down the food you consume, builds amino acids into useful proteins, delivers vitamins to certain parts of your body, and helps your blood clot so you don't bleed too much after an injury.
Liver neutralizer helps remove waste bilirubin - produced when red blood cells are broken down. If the liver is not working properly, too much bilirubin can build up in the body, leading to yellowing of the skin and whites of the eyes. A simple blood test can help your doctor find the cause of the problem.

3. Protect the liver
If injury or disease damages the liver, surgeons can sometimes remove up to 3/4 of the area. The liver usually grows back to its former size within a few weeks. If necessary, doctors can also sometimes use part of a donor liver to transplant a patient. The new liver will grow to match the recipient's body.
