About The Human Liver
What is the liver?
The liver is the largest internal organ in the human body and is one of the most complex organs. Reddish brown in color, it weights 1-3 pounds in adults, and is divided into four, unequal shaped and sized, lobes.


Where is the liver located in the body?
The liver is located in the upper right side of the abdomen, directly beneath the diaphragm and is protected by the rib cage.


What does the liver do?
The liver works 24 hours a day.

Your liver is responsible for:

CLEANING THE BLOODSTREAM
It acts as a filter to process and remove drugs, alcohol and other substances that may be harmful to the body. The liver neutralizes and destroys poisonous substances.

DEVELOPING NECESSARY BODY PROTEINS
The liver manufactures important proteins needed to nourish the body, to fight infections and provide normal blood clotting.

CONTROLING THE SUPPLY OF BODY FUELS
The liver acts as a filter to process and convert food into stored energy. It produces, stores and supplies that quick energy, called glucose, necessary to keep the body active and your mind alert. Additionally, the liver produces, stores and exports fat.

BALANCING HORMONES AND ASORBING VIATMINS
The liver maintains the balance of sex hormones, thyroid hormones, cortisone and other adrenal hormones. The liver assists in the absorption of vitamins and minerals (including vitamins A, E, D, K, and B12).

PRODUCING BILE
The liver produces bile, a greenish-yellow fluid, that carries away waste products. Bile is responsible for eliminating toxic substances along with aiding in digestion.

PRODUCING CHOLESTEROL IN THE BODY
The liver produces around 80 percent of the cholesterol in the body. It is responsible for regulating body cholesterol by producing it, excreting it and converting it to other essential substances.

Ways To Keep Your Liver Healthy

  • AVOID ALCOHOL
    Cirrhosis is caused by over-consumption of alcohol and may not surface until great damage has already been done.
  • WATCH FATTY FOODS
    The liver makes cholesterol from the foods you eat. Consuming healthy, well-balanced meals helps the liver to make appropriate amounts of cholesterol.
  • CONTROL MEDICATIONS
    All medications are chemicals. It is important that you take medication with your doctor's advice.
