Why does alcohol slow the brain's reaction?

Answer 1

its like a computer, the more you try to do the slower it gets.

Alcohol is quickly absorbed into the blood and can be measured within 40 to 70 minutes after you have consumed any alcoholic drink. The amount of alcohol in the blood reaches its highest level about an hour after drinking. However, food in the stomach may increase the amount of time it takes for the blood alcohol to reach its highest level. About 90% of alcohol is broken down in the liver. The rest of it is passed out of the body in urine and your exhaled breath.

Alcohol has a noticeable effect on the body, even when consumed in small amounts. When taken in large amounts, alcohol acts as a sedative and depresses the central nervous system. Because alcohol reduces tension and inhibitions, drinking tends to make people feel relaxed and confident. Even a low level of alcohol in the blood slows reactions. The more alcohol you drink, the greater your loss of normal mental and physical control. Drinking alcohol can cause a lack of coordination, blurred vision, slurred speech, and stupor (unresponsiveness). If you drink a large amount of alcohol over a short period of time, you may lose consciousness or die.

Alcohol enters the blood system, which is also feeding the brain with oxygen. the alcohol is removed from the blood by using water, which leads to dehydration.

Alcohol is removed from the bloodstream by a combination of metabolism, excretion, and evaporation. The relative proportion disposed of in each way varies from person to person, but typically about 90 to 98% is metabolised, 1 to 3% is excreted in urine, and 1 to 5% evaporates through the breath. A very small proportion (less than 0.5%) is also excreted in the sweat, tears, etc. Excretion into urine typically begins after about 40 minutes, whereas metabolisation commences as soon as the alcohol is absorbed, and even before alcohol levels have risen in the brain. (In fact, in some males, alcohol dehydrogenase levels in the stomach are high enough that some metabolization occurs even before the alcohol is absorbed.)

Metabolism is mainly by the group of six enzymes collectively called alcohol dehydrogenase. These convert the ethanol into acetaldehyde (an intermediate that is actually more toxic than ethanol). The enzyme acetaldehyde dehydrogenase then converts the acetaldehyde into non-toxic acetyl-CoA.

Memory, reactions to our senses are all handled by the brain, which uses chemical signals to identify a sense, map it to stored identifications in your memory, and then react to that stimuli. The extra chemicals in your brain interfere with the normal process.

Answer 2

becuase it does ... nah i looked it up on google it because:

Unlike food, alcohol does not have to be digested. The blood carries alcohol directly to the brain where it acts to slow down or depress brain activity. The remaining 80% is processed only slightly and absorbed into the blood stream more slowly through the gastro-intestinal tract. Alcohol gets into the blood stream so quickly that moments after it is consumed, it can be found in all tissues, organs and secretions of the body.

GABA is the major inhibitory neurotransmitter in the brain, and GABA-like drugs are used to suppress spasms. Alcohol is believed to mimic GABA's effect in the brain, binding to GABA receptors and inhibiting neuronal signaling.

Alcohol also inhibits the major excitatory neurotransmitter, glutamate, particularly at the N-methyl-d-aspartate (NMDA) glutamate receptor. And it releases other inhibitors, such as dopamine and serotonin. Consumption of even small amounts of alcohol increases the amount of dopamine in the nucleus accumbens area of the brain—one of the so-called "reward centers." However, it is most likely that the GABA and glutamate receptors in some of the reward centers of the basal forebrain—particularly the nucleus accumbens and the amygdala—create a system of positive reinforcement. In fact, multiple neurotransmitters in various parts of the brain combine to make the consumption of small doses of alcohol enjoyable.

The neurochemical effects of alcohol cause a range of short-term effects—from a mild buzz to slow reaction times, which make drunk driving so dangerous. In the long term, these effects are also the basis for two of the defining characteristics of addiction: tolerance and dependence

Answer 4

properly it relies upon on how a lot alcohol you devour interior of a given time period. in case you drink 6 beers in a million hour then your reaction time will be very sluggish and also you may want to slur your words and stumble somewhat. in case you drink 2 beers interior of two hours then you definately likely received't practice any indications of eating and no one might want to even understand. It basically relies upon on how a lot alcohol you drink and how briskly you drank it. you are able to have 6 beers interior of a few hours and be wonderful yet in case you drink 8 pictures interior of an hour then your reaction circumstances will be slower and how you act will be lots different then who you truly are.

Answer 5

Alcohol is a central nervous system depressant. "Depressant" means it retards the physical functioning of the nerve cells, of which your brain is entirely composed; it does not mean depressive in the emotional sense.

Answer 6

Because it's a POISON girl! It's NEUROTOXIC! That's as simple and direct as you will get it. Alcohol gives nothing, and can take everything. Stay Away!

Answer 7

yes it does because its a impairment just think of it this way when you drink, your brain becomes paralyzed and unable to function normal

Answer 8

the acid in it kills the brain cells and restricts the O2 take in

Answer 10

Its a depressant!!
