Transcript of ALCOHOL

What is Alcohol?
How do you eliminate alcohol from your system?
What is BAC?
Examples of Standard Drinks

Alcohol is a product of fermentation of yeast in the making of beer, whisky, wine, cider and vodka.

It contains an active drug which is the ethanol. It slows down the central nervous system and gives a false sense of reality .

It is also a depressant that slows down the messages travelling through the brain than enables the body to function.
How does BAC affect you when driving?
What is a standard
A standard drink is a drink that contains 10 grams of alcohol (12.5 mL pure alcohol).

By counting standard drinks you take, you can keep track of how much you're drinking and how that compares to the Australian Guidelines to reduce health risks from drinking alcohol.
A 425 mL of light beer is equivalent to a 285 ML of regular beer, a 100 mL of white and red wine, 60 mL of fortified wine, and a 30 mL of spirits.

You could not go beyond the standard drink because you'll be exceeding the limit and you may suffer a number of consequences.

Difficulty in understanding sensory information or impared vision
Difficulty in doing several tasks at once
Failure to obey road rules
Over confidence
Reduced reaction times
Feeling more relaxed and drowsy, which may cause the driver to fall asleep while driving

BAC is Blood Alcohol Concentration that refers to the amount of alcohol present in the person's blood stream.

A BAC of 0.05% means that there is 0.05 grams of alcohol in every 100 milliliters of blood.

0.05 grams of alcohol = 100 mL of blood
Light Beer = 425 mL
Regular Beer = 285 mL
Red Wine or White Wine or Champagne = 100 mL
Fortified Wine = 60 mL
Spirits = 30 mL
The Lab involved substituting alcohol drinks with water and food color while measuring different types of alcohol drinks in glasses.

At first, students estimated how much alcohol or liquor they think a standard drink and a serving size may have by pouring varied amounts of colored water into particular glasses.

After that, we were shown the correct
amount of alcohol in a standard
drink and in a serving size by
still using the colored water
and glasses.

What did you find
most interesting
or surprising?
From my findings, what I found interesting was that clubs usually don’t follow the measurement of standard drinks, but instead they follow the serving sizes which is more than what it really should be. They do this because it is more convenient for them and so that people would tend to keep on coming back to their establishment. The more a person drinks liquor, the more their mind and body system craves for the drink. The more a person craves, the more they keep on coming back to clubs, especially when they get more of what they pay.
It proved that there is a distinct difference between standard drinks and serving sizes in terms of figures and definition.
It also proved that when you go to clubs, and when they give you liquor, they don’t serve it in the amount of a standard drink. They serve it in serving sizes which is in a way that is more convenient for the bartenders and the drinkers because liquors served in cans or bottles.
What did it prove?
What did the lab involve?
What are the general effects of alcohol?
What is Binge Drinking?
Binge drinking is drinking too much in a short period of time with the intention of being drunk. This can be very dangerous to a person's health especially to young people.
Why is Binge Drinking dangerous?

Binge drinking is very dangerous because it increases the risks of health problems and hinders further development while still at a young age, and it can lead young people to take risks, impair their decision making and put themselves in very dangerous situations that could take people's lives as well as theirs.
What are the factors affecting BAC?
Rate of consumption - how much alcohol you have drunk
Drink Strength - how strong are you in drinking alcohol
Fitness Level - are you physically active or not
Age - how old you are
Emotional State - what are you feeling
Period of time which you drink - what time did you start drinking
Medications taken - what type of medicine are you taking
State of liver - is your liver in good condition
Regular drinker or not - do you drink regularly
Empty Stomach - what was the last food you ate
What are the effects of alchol on the body and blood?
General effects:
Effects on the body:

Liver diseases - liver inflammation, alcoholic hepatitis, fibrosis, cirrhosis
Complications in the heart - stroke, high blood pressure, arrhythmias
Complications in the brain - interferes brain's communication pathways
Fetal alcohol syndrome (pregnant women) - endangers the baby's development while inside the mother's womb
Physical injury to yourself and other people
Destroys immune system that makes the body prone to more diseases
Death due to accidents or complications of organs in the body
Effects on the blood:
Alcohol consumption can cause decreased
healthy blood cell production and these blood cells cannot mature into functional cells.
Alcohol destroys red blood cells resulting in anemia.
Alcohol also interferes with the production and function of white blood cells, especially the cells that defend the body against invading bacteria. This makes alcoholics suffer more bacterial infections.
Alcohol affects the platelets and blood-clotting system and increases the suffering of a stroke.

Feeling of warmth
Flushed skin
Impaired judgement
Decreased nervous feeling
Musular incoordination
Slurred speech
Memory and comprehension loss

In case of extreme intoxication:
Poor breathing
Fall in blood pressure

Severe alcohol poisoning:
Serious injuries
Most of the alcohol in the body (about 91 per cent) is broken down by the liver. A small amount also leaves the body in urine, sweat and the breath. Since the liver can only break down about three quarters of a standard drink an hour, sobering up takes time. Food absorbs the liquor and it slows down how it was absorbed by the body. Cold showers, exercise, black coffee, fresh air or vomiting will not speed up the process.

It takes the LIVER 1 hour to remove a standard drink.

As a rule of thumb, an average person can eliminate
0.5 oz (15 ml) of alcohol per hour. So, it would take approximately one hour to eliminate the alcohol from a 12 oz (355 ml) can of beer.
