Which organs are commonly affected by toxic substances due to their roles in metabolism and excretion?

  1. Heart and muscles

  2. Liver and kidneys

  3. Brain and spinal cord

  4. Stomach and intestines

The correct answer is: Liver and kidneys

Toxic substances can affect various organs in the body, but the specific organs most commonly affected are the liver and kidneys. This is because the liver and kidneys have important roles in metabolism and excretion. The liver is responsible for filtering and processing toxins from the body, while the kidneys help remove these toxins through urine. The heart and muscles (option A) may also be affected, but they do not play as significant of a role in metabolizing and excreting toxins. The brain and spinal cord (option C) are not commonly affected by toxic substances unless they are specifically targeting the nervous system. The stomach and intestines (option D) may experience some effects from toxic substances if ingested, but they do not play a major role in metabolism and excretion like the liver and kidneys do.
