Final answer:
A buildup of lipids in the liver tissue is known as Steatosis, which occurs when the lipid content in the liver rises significantly, leading to fatty liver conditions.
Step-by-step explanation:
A buildup of lipids that are deposited in the liver tissue is known as Steatosis. This condition is characterized by the abnormal accumulation of fats in the liver when the lipid content increases significantly, typically from the normal 5% to about 25% to 30%. Steatosis can be classified into two types: Physiological fatty livers, which occur due to excess mobilization of fatty acids to the liver, and Pathological fatty livers, which arise when the liver is unable to produce lipoproteins to clear the lipids due to defects or infections. Cirrhosis, on the other hand, is the formation of fibrous tissue in the liver, replacing dead liver cells, often due to causes such as viral hepatitis and alcoholism, and leads to progressive loss of liver function. Thus, the correct answer to the question is A. Steatosis.
