In what organ is most alcohol processed in the body?

The liver is the primary organ responsible for processing alcohol in the body. When alcohol is consumed, it enters the bloodstream and is transported to the liver, where enzymes, particularly alcohol dehydrogenase (ADH), are involved in metabolizing the alcohol. This process breaks alcohol down into acetaldehyde, which is further processed and eventually eliminated from the body. The liver can metabolize a certain amount of alcohol at a time, but excessive consumption can overwhelm its capacity, leading to potential liver damage or diseases such as fatty liver, hepatitis, or cirrhosis.

The other organs mentioned perform different functions that are not directly involved in alcohol metabolism. The heart, while essential for circulating blood and distributing nutrients, does not play a role in processing alcohol. The kidneys function primarily in filtering blood and excreting waste products through urine, but they do not metabolize alcohol. The stomach is involved in the initial absorption of alcohol into the bloodstream but is not considered a primary organ for its processing. Thus, the liver is uniquely equipped for the task, making it the correct answer.
