STOMACH
Some alcohol is absorbed; 20-30% is broken down by alcohol dehydrogenase

So, how does impairment So, how does impairment occur?occur?
Blood Alcohol Concentration - BACBlood Alcohol Concentration - BAC The amount of alcohol in a person’s bloodstream. The amount of alcohol in a person’s bloodstream.

Blood Alcohol ConcentrationBlood Alcohol Concentration
The amount of alcohol in a person’s bloodstream. The amount of alcohol in a person’s bloodstream.
Tolerance does NOT effect BAC. BAC will continue to rise! With tolerance, the onset of physical characteristics of impairment may not directly correlate with BAC.
Does a person’s tolerance effect Does a person’s tolerance effect their BAC?their BAC?

Tolerance: needing more and more of a substance to get the
same effect
So does tolerance affect BAC?
NO! If you drink, BAC is going to rise; however if you have a high tolerance, the onset of physical characteristics of intoxication may not directly correlate with a person’s BAC.

MOUTHMOUTH
STOMACHSTOMACH
- Alcohol enters the body - Up to 5% of the alcohol is absorbed
- 20% of the alcohol is absorbed- 20-30% of alcohol is metabolized by alcohol dehydrogenase- travels through the pyloric valve to the small intestine
![Page 20: Understanding Alcohol. Ethanol: psychoactive drug in alcoholic beverages ALCOHOL.](https://reader036.fdocuments.us/reader036/viewer/2022062802/56649ebf5503460f94bc9cf0/html5/thumbnails/20.jpg)
SMALL INTESTINESMALL INTESTINE- The remainder of the alcohol is absorbed
HEARTHEART- Pumps alcohol throughthe body-Blood vessels dilate

BRAINBRAIN
-Depresses the cerebral cortex
-Pituitary gland releases antidiuretic hormone (ADH) and urine production increases

LIVERLIVER-Metabolism occurs
-Liver prioritizes the breakdown of alcohol over it’s normal functions.
KIDNEYSKIDNEYS
- Excreted from the body as urine
