Which substance is defined as a substance that causes liver damage?

• A. Hepatotoxin
• B. Nephrotoxin
• C. Neurotoxin
• D. Hematopoietic toxin

Answer: (A)

A hepatotoxin is a substance that damages the liver. The prefix hepato- refers to the liver, so a toxin that targets the liver is described as hepatotoxic. The liver is the body's main organ for detoxification, and its cells can be injured by various chemicals, especially when metabolism creates reactive intermediates or when bile formation or other liver functions are disrupted. This is often reflected in elevated liver enzymes such as ALT and AST and other signs of liver dysfunction. The other terms describe toxins that affect different organs or systems: nephrotoxins harm the kidneys, neurotoxins affect the nervous system, and hematopoietic toxins impact blood cell formation.
