The human liver is something of a workhorse. It removes toxins from the blood, helps with digestion, fights infections and regulates blood sugar and cholesterol levels. Every time it filters alcohol, however, some of the liver’s cells die. Fortunately, the liver is a hardy organ and can regenerate itself, undoing much of this injury.
In fact, studies have shown that a liver can regrow itself back to a normal weight even after as much as 90 percent of its tissue has been removed – and nor does it take long to do so. The human liver can re-establish its normal weight within just 15 days. All this makes the liver unique among organs.
