Alcohol and its Effects Alcohol can be a very harmful substance. Alcohol can be abused, and people can get addicted to it like any other drug. It can impair coordination and judgment as well as a lot of other things. Alcohol can also have long term effects on the organs in the body. It can affect people psychologically as well as behaviorally. Many deaths that occur each day are caused by alcohol. Consuming alcohol affects a lot of things that people do not realize. Psychoactive drugs affect the nervous system (Seymour & Smith, 2013). These types of drugs affect consciousness and moods. Types of psychoactive drugs include depressants, stimulants, and hallucinogens (King, 2013). Alcohol is a depressant that affects the central nervous system causing decreased blood pressure and heart rate (Grunberg, Berger, & Hamilton, 2011). Depressants mainly slow down, or depress, the activity in the brain. Alcohol stimulates dopamine neurons in the VTA or the ventral tegmental area of the midbrain (Olsen, 2011). The VTA and the NAc (nucleus accumbens-olfactory tubercle complex) make up the dopamine reward circuit, which reinforces the effects of drugs (Olsen, 2011). This reinforcement makes the user feel good, and they associate alcohol with this pleasurable feeling. Other areas of the body besides the brain are affected by alcohol consumption. Some major organs it can affect include the heart, stomach, and the liver. Frequent use of alcohol is a major cause of cardiomyopathy, which is a chronic disease of the heart (Manzo-Avalos & Saavedra-Molina, 2010). The muscles of the heart become flaccid and can even degenerate. If the heart muscles are weakened, this means the heart isn’t working correctly, and the heart cannot pump blood through the body as efficiently as it should. When alcohol is consumed, it is absorbed fairly quickly in the stomach and gastrointestinal tract. Alcohol can

    But what really goes on inside our brain when we consume alcohol that causes such effects? Once alcohol has reached the brain it can have quite a significant effect on how the brain functions. The more alcohol consumed, the further it goes into the brain, causing worse effects. A study examining thirteen (13) areas of the brain (frontal lobe, parietal lobe, temporal lobe, occipital lobe, basal ganglia, thalamus, limbic system, midbrain, cerebellum, insular, anterior cingulated gyrus, posterior cingulated gyrus, and paracentral) during intoxication showed decreased absolute metabolism for all thirteen (13) areas. However, there were three (3) areas which showed the greatest affect. Those were the occipital lobe, which controls vision, the cerebellum cortex which has to do with balance, attention, and movement, and then the temporal lobe which handles hearing. Alcohol interferes with communication between nerve cells in the brain by suppressing the activity of excitatory nerve pathways and increasing activity of inhibitory nerve pathways. This is why we see drunken people become sluggish in their…

    Alcohol is a depressant, which means it slows the function of the central nervous system. Alcohol actually blocks some of the messages trying to get to the brain. This alters a person's perceptions, emotions, movement, vision, and hearing. Alcohol can help a person feel more relaxed or less anxious. More alcohol causes greater changes in the brain, resulting in intoxication. People who have overused alcohol may stagger, lose their coordination, and slur their speech. They will probably be confused and disoriented. Intoxication can make someone very friendly and talkative or very aggressive and angry. People who are intoxicated may think they're moving properly when they're not. They may act totally out of character. When large amounts of alcohol are consumed in a short period of time, alcohol poisoning can result. Violent vomiting is usually the first symptom of alcohol poisoning. Extreme sleepiness, unconsciousness, difficulty breathing, dangerously low blood sugar, seizures, and even death may result. From a very young age, kids see advertising messages showing beautiful people enjoying life and alcohol. And because many…

    To start off, the consumption of alcohol can and will cause significant physical damage to the body and mind. This is in the interest of alcohol being absorbed into the bloodstream, which affects the central nervous system and has such an immense control over all body functions. A human brain has not fully developed until the age of 25, which is why the legal drinking age should not be at the age of 21. It gives off harmful alterations in the functions of the development of the brain and therefore doesn’t give the brain the full amount of time that it needs to grow. While the brain is still developing, drinking a heavy amount may cause damages to certain brain functions and have lasting health effects. Some examples to body functions that can…
