LUNGS Some alcohol is exhaled through the breathing process. This is why you can smell alcohol on a person’s breath Exceptionally high alcohol levels can result in unconsciousness, coma and even death through the suppression of the brain's breathing center, the cerebellum.

LIVER v. Alcohol is oxidized or metabolized by the Liver v. Alcohol is typically broken down at a pace of 1 drink per 1 -2 hours v. Long-term heavy drinking : v Fat accumulates in the liver v Eventually become non-functional due to scar tissue v Cirrhosis This is the 6 th leading cause of adult deaths in the United States.

*LONG-TERM EFFECTS: Cirrhosis of liver. Cancers of body organs, heart disease, ulcers, and early death. 1 out of 10 people in the U.

HOW DOES ALCOHOL TRAVEL THROUGH THE BODY? Once alcohol reaches the stomach it begins to break down the alcohol dehydrogenate enzyme. (Women produce less) 20% of the alcohol then enters the blood. Alcohol is then absorbed in the upper portion of the small intestine.

HOW DOES ALCOHOL TRAVEL THROUGH THE BODY? The alcohol-laden blood then travels to the liver via the veins and capillaries of the digestive tract. The liver cells are the only cells in our body that can produce enough enzyme to oxidize alcohol at a decent rate. Alcohol effects all organs, but its most dramatic affect is on the liver.
