The liver is one of the most important organs in your body yet many people have no idea what it actually does. Every day your liver performs hundreds of vital tasks that keep you alive, from cleaning your blood to helping you digest food. If your liver stopped working for even a short time, your entire body would begin to fail.
So what does the liver do exactly and why is it called the body’s chemical factory This detailed guide explains the real functions of the liver in simple language so anyone can understand.
What Does the Liver Do
The liver is a large reddish brown organ located on the upper right side of your abdomen under the rib cage. It is the only internal organ that can regenerate itself which shows how powerful and essential it is.
Here are the main things the liver does every single day.
It filters toxins from the blood
It processes everything you eat or drink
It stores energy in the form of glycogen
It produces bile to digest fats
It regulates hormones
It controls cholesterol levels
It supports your immune system
Without the liver performing these jobs your body cannot survive.
How the Liver Helps With Digestion
One of the liver’s most important roles is digestion.
When you eat fatty foods your body cannot digest fat without help. The liver produces a substance called bile. Bile is stored in the gallbladder and released into the small intestine.
Bile breaks down fats into smaller particles so your body can absorb them. Without bile you would feel bloated weak and unable to get nutrients from food.
This is why people with liver disease often feel tired after meals.
How the Liver Detoxifies the Blood
Everything you eat drink breathe or absorb through your skin passes through your liver.
The liver removes harmful substances like
Alcohol
Drugs
Pollution toxins
Chemicals from food
Waste from dead blood cells
It turns these dangerous substances into harmless waste which leaves the body through urine or stool.
This is why excessive alcohol or drug use damages the liver because it becomes overwhelmed with toxins.
How the Liver Stores Energy
Your body needs a constant supply of energy.
The liver stores extra sugar in the form of glycogen. When your blood sugar drops between meals or while sleeping the liver releases glycogen back into the bloodstream.
This keeps your brain and muscles working properly even when you are not eating.
How the Liver Produces Important Proteins
Your blood needs special proteins to function correctly and the liver makes most of them.
These proteins help
Blood clot when you are injured
Transport oxygen and nutrients
Support the immune system
Maintain fluid balance
People with liver damage bleed easily because their liver cannot make enough clotting proteins.
How the Liver Regulates Hormones
Hormones control everything from mood to growth to reproduction.
The liver breaks down excess hormones so your body stays balanced. When the liver is weak hormones build up and cause problems like acne mood swings or infertility.
How the Liver Supports the Immune System
Your liver is part of your immune defense.
It removes bacteria and viruses from the blood and produces immune proteins that fight infections.
This is why people with liver disease get sick more often.
