Final answer:
Cirrhosis of the liver is a severe condition marked by fibrous tissue accumulation, which leads to progressive liver function loss and, in advanced stages, may only be treated with a liver transplant.
Step-by-step explanation:
Cirrhosis of the liver is a condition characterized by the accumulation of scar tissue in the liver, leading to its irreversible damage. Cirrhosis is the formation of fibrous tissue in the liver, which replaces dead liver cells that can die due to various causes, including viral hepatitis, alcoholism, or exposure to other liver-toxic chemicals. These conditions result in a progressive loss of liver function. Furthermore, in cirrhosis, the liver doesn't function well, meaning blood traveling through it may not be properly detoxified. When the damage to the liver is severe, the only treatment option may be a liver transplant.
