Which of the following body parts is involved in eliminating alcohol from the body?

The kidney plays an essential role in filtering and excreting various substances from the bloodstream, including some waste products and toxins. While the primary organ responsible for metabolizing alcohol is the liver, the kidneys contribute to the elimination of alcohol by excreting it through urine. They filter the blood and can remove excess water and small amounts of alcohol, helping regulate the body’s fluid balance and maintain homeostasis.

In contrast, other organs listed serve different functions. The heart is primarily responsible for pumping blood throughout the body and does not directly process or eliminate alcohol. The pancreas is involved in digestion, particularly in the release of enzymes and insulin, and does not play a direct role in alcohol elimination. The brain processes alcohol by affecting neurotransmitter systems and behavior but does not eliminate it from the body.
