T/F

Ethanol is a small, water soluble molecule that requires no digestion It can be easily absorbed throughout the length of the GI tract by simple diffusion

Definition
True
Term
Why is alcohol consumed more slowly when food is present in the stomach?
Definition
Food stimulates stomach secretions, which serve to dilute alcohol, thereby slowing its absorption into the bloodstream. Blood alcohol level will rise more quickly when alcohol is consumed on an empty stomach.
Term

Term
Where can Alcohol dehydrogenase be found in the human body
Definition
Although the liver is the chief site for the metabolism (detoxification) of alcohol, there is some of this enzyme present in the stomach as well.
Term
What happens to the liver if it is abused by prolonged alcohol overuse
Definition
liver fat deposits increase and can choke off blood vessels, depriving liver cells of life sustaining nutrients and oxygen. Liver cells begin to die and are replaced by scar tissue. Hemorrhaging of the liver may also occur. If too many liver cells die, the liver may not survive. This is called "cirrhosis of the liver".
Term
Why do biddies get more crunk than bros
Definition
There appears to be lower activity of alcohol dehydrogenase in the stomach of women.  Therefore, per alcoholic drink, more alcohol reaches the bloodstream in a woman than in a man.  In addition, a woman's body weight contains a higher percentage of adipose (fat) tissue and a lower total body water content when compared with men. Since alcohol diffuses into the water compartments of the body, it will be more concentrated in a woman's body water.
Term

Definition
(True) This brings blood quickly to the surface of the body, releasing heat, which explains the feeling of warmth people experience immediately after drinking alcohol.

Term
Are there any beneficial effects of consuming alcohol
