In humans, the liver is very important because of the numerous functions it performs. Scientists say this vital organ, being one of the largest in humans, detoxifies the body by ridding it of harmful substances, while it also produces the biochemical substances that are necessary for proper digestion of food.
The presence of a healthy liver in the body is what makes the blood what it is, experts say, as the liver produces the albumin – a major component of blood serum.
A General Practitioner, Dr. Daniel Ogunboyejo, says when a woman is pregnant, in the first three months, the liver is the main site of red blood cell production in the foetus. And even after the baby is born, this organ produces the hormone that plays an important role in the child's growth and continues to aid the building up of organs and tissues in adults.
Ogunboyejo also notes that when a person's blood pressure becomes low (hypotension), the liver, working in tandem with the kidneys, produces angiotensinogen – a hormone that is responsible for raising the blood pressure when activated by another enzyme (renin) that is released when the kidney senses low blood pressure.
Experts say the liver is thought to be responsible for up to 500 separate functions, usually in combination with other systems and organs. And that is why they conclude that this organ is necessary for survival, as there is no way to compensate for its absence in the body in the long term.
Scientists say the liver is basically the 'body's filter.' The function of the liver is to process medications, alcohol, and other such chemicals and toxins and remove them from the body. "Therefore, anything you put into your body will, at some point and in some form, pass through the liver," Ogunboyejo warns.
Liver destroyers
At a media briefing about Hepatitis C, a specialist in hepatology, gastroenterology and endoscopy, Dr. Aderemi Oluyemi, warns that numerous activities can jeopardise the liver, leading to damages that are sometimes irreversible unless the patient goes for liver transplantation – an extreme and expensive procedure that is not available in the country.

Abusing anabolic steroids
Many people, especially athletes, body builders and weight lifters, use anabolic steroids without supervision by a competent physician. Yet experts say these synthetic variants of the male sex hormone (testosterone), if used regularly and for a long period, can raise the risk of developing liver cancer as well as some other cancers.
It can also result in liver tumours; the liver may be enlarged, become deep red in colour and fragile.
"It may also lead to haemorrhagic cystic degeneration of the liver – a rare condition that requires urgent surgery," Ogunboyejo notes.
