Which organ of the body is most affected by excessive intake of alcohol?
Organs such as the brain, which contain a lot of water and need a lot of blood to function, are particularly vulnerable to the effects of alcohol. Alcohol makes the liver, which is the major organ that processes alcohol, work very hard.
In which organ in the human body is alcohol broken down?
Alcohol is metabolized in the body mainly by the liver. The brain, pancreas, and stomach also metabolize alcohol.
