Understanding Your Liver
Discover the remarkable functions and vital importance of one of your body's most powerful organs. The liver is your body's chemical factory, working tirelessly to keep you healthy.
What Is the Liver?
The liver is the largest internal organ and gland in the human body, performing over 500 essential functions to help keep you alive and healthy.
A Vital Organ
The liver is a wedge-shaped, reddish-brown organ located in the upper right part of the abdominal cavity, beneath the diaphragm and above the stomach, right kidney, and intestines.
It is one of the most important organs in the body and also has the special ability to regenerate itself. Even when part of the liver is damaged, it can often grow back under the right conditions.
Liver Structure
Two Main Lobes
- •Right Lobe: The larger lobe, making up most of the liver.
- •Left Lobe: The smaller lobe, divided by the falciform ligament.
Additional Components
Hepatocytes
Special liver cells that carry out most liver functions.
Bile Ducts
Small channels that move bile to the gallbladder and digestive tract.
Blood Supply
The liver receives blood through the portal vein and hepatic artery.
Liver Functions
Your liver performs over 500 vital functions every day. Here are some of the main roles that help keep your body working properly.
Metabolism
Processes nutrients from food and turns them into energy and materials the body can use.
- •Breaks down carbohydrates into glucose for energy
- •Converts extra glucose into glycogen for storage
- •Metabolizes proteins and fats for different body functions
Detoxification
Filters and removes harmful substances from the blood, helping protect the body from toxins.
- •Neutralizes drugs, alcohol, and other toxic substances
- •Removes bacteria and old blood cells from circulation
- •Converts ammonia into urea for safer elimination
Bile Production
Produces bile to help digest fats and absorb fat-soluble vitamins in the small intestine.
- •Creates around 800 to 1000 ml of bile daily
- •Helps break down dietary fats
- •Supports absorption of vitamins A, D, E, and K
Storage
Stores essential vitamins, minerals, and energy reserves for when the body needs them.
- •Stores vitamins A, D, E, K, and B12
- •Maintains iron and copper reserves
- •Stores glycogen as an energy reserve
Protein Synthesis
Creates important proteins needed for blood clotting, immunity, and tissue repair.
- •Produces albumin for blood volume regulation
- •Creates clotting factors that help stop bleeding
- •Synthesizes proteins important for immune support
Waste Management
Processes and helps remove waste products formed during metabolism and cell breakdown.
- •Breaks down old red blood cells
- •Processes bilirubin for excretion
- •Helps eliminate metabolic waste products
The Body's Chemical Factory
Every minute, your liver processes a large amount of blood while carrying out many chemical reactions at the same time. It is one of the hardest-working organs in the body, working continuously to support health and survival.
