Each of us has embedded in our bodies a God given chemical factory, so complex that it cannot be reproduced by human engineers. This factory is working unnoticed every moment, eliminating poisons and creating vital nutrients.
An adult human liver normally weighs between 1.4-1.6 kg (3.1-3.5 lb), and is a soft, pinkish-brown, triangular organ. Averaging about the size of an American football in adults, it is the largest internal organ in the human body. The liver lies on the right side of the abdominal cavity beneath the diaphragm. The lower part of the rib cage covers the liver, protecting it from injury.
The liver is necessary for survival; there is currently no way to compensate for the absence of liver function. There is no artificial organ or device capable of emulating all the functions of the liver. If a person's liver does fail, a device the size of a small cabinet can keep him alive for a few days. That is the most human engineers can currently do to replicate the liver.
One and a half liters of blood pass through the liver every minute and the liver holds 13% of the body's blood at any given time. (This explains why Jews must broil chicken or beef liver. Jews may not eat blood. Due to liver's high blood content, salting is not sufficient to draw out the blood. Liver can be koshered only by a special broiling process.)
The liver contributes to more than 500 vital functions in the body.
The liver's four most important tasks are:
1. Purification: changing harmful chemicals and toxins to harmless substances and eliminates them.
2. Synthesis: takes the simple building blocks of food to syntheize complex substances.
3. Storage: sugars, fats and vitamins are stored until needed by the body.
4. Transformation: the essential building blocks are changed to be use in other ways by the body.
This miracle of divine engineering is silently working away every moment of our lives. We could not survive more than a few hours without it. Let's spend a little time contemplating this immense gift from God and grow in our love for Him.
