Gastric ADH in the Stomach
An enzyme that begins to break alcohol
down in the stomach
Alcohol then passes into the small
intestine where it is absorbed into the
blood stream.
Females have less ADH
Onto the LIVER!
Alcohol is then transported to the liver
Here alcohol oxidation takes place and converts
alcohol into 2 waste products:
carbon dioxide and water
