Introduction

Name and background of the speaker.

State goal of today’s lecture. Understand the affects of alcohol on the human body.

Besides caffeine, alcohol is used by most people in the world.

Question – What animals can process alcohol in their body?

Body

History of Alcohol

1. Archaeological evidence – 6400 B.C. during the Neolithic period.

2. During the 20th century the invention of distilling allowed for increasing, or fortifying the alcoholic content of beverages.

3. Does anyone know what the maximum alcohol content of wine and beer is without infusing alcohol into the beverage?

4. Is there a limit to natural fermentation?

Types of Alcohol

1. Beer

2. Wine

3. Distilled beverages

4. What is the difference between proof vs. percentage of alcohol? Where did they come up with proof?

A. Alcohol’s Properties

Alcohol is a term denoting a family of organic chemicals with common properties made up of carbon, oxygen and hydrogen.

a. Ethanol

b. Methanol

c. Isopropanol

B. Ethanol

1. A clear volatile liquid that burns easily.

What is another term for burning?

2. Alcohol is what?

a. A central nervous system depressant.

b. What parts of the brain does alcohol impact, and how?

i. 0.03 –0.12 BAC

Judgement/higher brain functions, increased self-confidence, decreased inhibitions, beginning of sensory motor impairment, fine motor functions.

ii. 0.09 – 0.25 BAC

Impairment of perception, memory, reaction time, visual acuity, impaired balance, decrease in sensory motor coordination.

iii. 0.18 – 0.30 BAC

Disorientation, confusion, dizziness, disturbances of vision, perception of color, form, motion and dimensions, increased pain threshold, lack of muscular coordination, slurred speech.

iv. 0.25 – 0.4 BAC

Approaching loss of motor functions, decreased response to stimuli, lack of muscular coordination, inability to stand or walk, vomiting, impaired consciousness.

v. 0.35 – 0.5 BAC

Complete unconsciousness, subnormal body temperature, impairment of circulation and respiration, possible death.

vi. 0.45+ BAC

Death

C. Alcohol pathway

1. Stomach - 20 to 25% is absorbed

2. Small intestines – 75 to 80% is absorbed.

3. Alcohol has a high affinity for water. It will therefore disperse in the body very quickly.

a. Blood alcohol concentration is a function of total amount of alcohol in the body divided by the amount of water in the body.

b. So could body weight or type have a relationship in how alcohol affects the body?

c. How about gender?

d. Consumption rate?

e. Medication

f. Fatigue?

g. Tolerance?

i. Metabolic tolerance – Up to 72% higher in chronic users.

ii. Functional tolerance – Changes in how alcohol is tolerated by the body.

h. Age?

i. Ethnicity?

4. Peak concentrations - Between 0.5 to 2.12 hours after consumption.

a. What could effect the time it takes to reach peak concentration?

b. Food?

i. Fasting – 0.5 to 2.12 hours.

ii. Non-fasting – 0.75 to 2.12 hours

c. Why?

d. Pyloric valve.

5. Elimination is accomplished in the liver (95%).

a. How?

b. How fast?

6. Exposure to Fatal Vision Goggles.
