Which of the following has primary responsibility for eliminating alcohol from the bloodstream

A. Stomach
B. Liver
C. Spleen
D . Both A and c

Answer: The liver is primarily responsible for eliminating alcohol from the bloodstream. While a small amount of alcohol may be broken down by the stomach and spleen, the vast majority of alcohol metabolism occurs in the liver. Therefore, option B is the most accurate answer.


A. Stomach: When a person consumes alcohol, a small amount of it is broken down in the stomach by an enzyme called alcohol dehydrogenase (ADH). However, this only accounts for about 20% of the alcohol metabolism in the body. The rest of the alcohol travels to the small intestine, where it is absorbed into the bloodstream and transported to the liver.

B. Liver: As mentioned earlier, the liver is primarily responsible for eliminating alcohol from the bloodstream. The liver breaks down alcohol using a two-step process. First, ADH breaks down alcohol into acetaldehyde, which is then broken down further into acetate by the enzyme aldehyde dehydrogenase (ALDH). The acetate is then converted into water and carbon dioxide and eliminated from the body.

C. Spleen: The spleen plays a role in the immune system and helps filter the blood. While it is true that the spleen can break down some alcohol, this accounts for a very small amount of the total alcohol metabolism in the body. Therefore, it is not a primary site of alcohol elimination.

In summary, while both the stomach and spleen play a role in alcohol metabolism, the liver is the primary site of alcohol elimination in the body.

Which organ is responsible for metabolizing alcohol quizlet?

The liver is primarily responsible for metabolizing alcohol. It produces enzymes, specifically alcohol dehydrogenase and acetaldehyde dehydrogenase, which break down alcohol into acetaldehyde and then into less harmful substances such as carbon dioxide and water.

What can help slow the absorption of alcohol into the bloodstream?

Several factors can help slow the absorption of alcohol into the bloodstream:

Eating: Consuming food before or while drinking alcohol can slow down its absorption. The presence of food in the stomach delays the passage of alcohol into the small intestine, where most absorption takes place. Foods high in fats and proteins are particularly effective in slowing alcohol absorption.

Drinking slowly: Pace your alcohol consumption by sipping slowly rather than taking frequent large drinks. This allows your body more time to metabolize alcohol as it enters the system.

Hydration: Staying hydrated by drinking water or non-alcoholic beverages alongside alcohol can help slow absorption. It helps dilute the alcohol in your system and can reduce the concentration of alcohol in your bloodstream.

Avoiding carbonation: Carbonated alcoholic beverages, such as beer or sparkling wine, can increase the rate of alcohol absorption. Opting for non-carbonated options can help slow down absorption.

Alcohol concentration: Choosing beverages with lower alcohol content can also slow the rate of absorption. Drinks with higher alcohol content, such as spirits or shots, are absorbed more rapidly than lower alcohol beverages like beer or wine.

It’s important to note that while these measures can help slow alcohol absorption, they do not eliminate the effects of alcohol or prevent impairment. The best way to ensure safety is to drink responsibly and in moderation, or abstain from alcohol altogether if you are unable or choose not to consume it.

How is alcohol primarily eliminated from the body?

Alcohol is primarily eliminated from the body through a process called oxidation, which occurs primarily in the liver. The liver produces enzymes, specifically alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH), which metabolize alcohol.

Alcohol Dehydrogenase (ADH)

ADH converts alcohol (ethanol) into acetaldehyde by removing hydrogen atoms. This reaction occurs mainly in the liver. ADH is responsible for the initial step in alcohol metabolism.

Acetaldehyde Dehydrogenase (ALDH)

Acetaldehyde, the product of ADH metabolism, is further metabolized by ALDH. ALDH converts acetaldehyde into acetic acid, which is eventually converted into carbon dioxide and water. This final step occurs in various tissues, including the liver and other organs.

These metabolic processes involve the oxidation of alcohol to acetaldehyde and then to acetic acid. The resulting acetic acid is further metabolized into carbon dioxide and water, which can be eliminated from the body through exhalation, urine, and sweat.

The rate of alcohol metabolism varies among individuals, but it generally follows a relatively constant rate, commonly referred to as a “standard drink per hour.” On average, the liver metabolizes approximately one standard drink (containing about 14 grams of pure alcohol) per hour. Factors such as body weight, sex, genetics, liver health, and other medications or substances can influence the rate of alcohol metabolism.

It’s important to note that alcohol metabolism occurs at a relatively constant rate, regardless of methods or remedies claimed to accelerate the process (e.g., drinking coffee, exercising, or taking certain supplements). The only effective way to sober up and eliminate alcohol from the body is through time, allowing the liver to metabolize alcohol naturally.

What is the best way to reduce alcohol in the body?

The most effective way to reduce alcohol levels in the body is to allow time for it to metabolize naturally. The liver processes alcohol at a rate of about one standard drink per hour, depending on various factors such as body weight, metabolism, and overall health. While there are no quick fixes or guaranteed methods to expedite the process, there are a few things you can do to support your body in reducing alcohol levels:

Stop drinking alcohol: The first step is to discontinue consuming alcohol. This gives your body a chance to focus on metabolizing the alcohol already present in your system.

Hydrate: Drinking plenty of water can help dilute the alcohol in your system and support kidney function, aiding in the elimination of alcohol through urine.

Eat a balanced meal: Consuming a meal that includes carbohydrates, proteins, and fats can help slow down alcohol absorption. Food in the stomach can also assist in reducing the intensity of alcohol’s effects.

Get some rest: Giving your body time to rest and recover can contribute to the natural breakdown of alcohol. Sleep allows your body to heal and restore itself.

Be patient: Time is the key factor in reducing alcohol levels. It’s essential to allow your body the necessary time to process and eliminate alcohol naturally. Trying to speed up the process can be dangerous and may lead to risky behaviors.
