Which organ is primarily responsible for removing alcohol from the body?

Explanation:
The liver is the main organ that clears alcohol from the body. It uses enzymes to metabolize ethanol first into acetaldehyde and then into acetate, which are eventually broken down into water and carbon dioxide to be eliminated. This metabolic process happens most of all in the liver, so it handles the bulk of alcohol removal. A small amount is removed through other routes—some alcohol is exhaled in the breath and a little is excreted in urine—but these pathways contribute far less than the liver's metabolism. Because the liver can process alcohol at a limited rate—roughly one standard drink per hour for many people—drinking more than that slows clearance and keeps you impaired longer, which is important to consider for safe driving.
