Which option is not a reflex used for toxin elimination, waste elimination, or detoxification?

• A. Skin, entire foot
• B. Liver
• C. Larynx
• D. Kidneys

Answer: (C)

Elimination of toxins and waste mainly involves organs that actively detoxify or excrete. The skin contributes through sweat, the liver detoxifies chemicals and processes metabolites, and the kidneys filter and excrete waste from the bloodstream. The larynx, while part of the airway, isn’t a detoxification or waste-elimination organ. Its reflexes, such as coughing, serve to protect the airway by expelling irritants, not to detoxify the body. So the larynx is not a reflex pathway used for toxin elimination, waste elimination, or detoxification.
