This page delves into the specific effects of alcohol on the human body, explaining its classification as a depressant and its impact on various bodily functions. It provides a detailed look at how alcohol consumption affects a person's behavior and physical state.
Vocabulary Ethanol is the type of alcohol found in alcoholic beverages that affects the central nervous system.
The text describes how ethanol is absorbed into the bloodstream and travels to the brain, where it slows down the nervous system. This slowing effect is why alcohol is classified as a depressant.
Example The effects of alcohol consumption range from feeling relaxed and happy with small amounts to loss of muscle control, slurred speech, and even unconsciousness with excessive consumption.
The page also includes information about the alveoli in the lungs, explaining their structure and function in gas exchange. This information seems somewhat out of place in the context of alcohol effects but may be relevant to understanding how substances interact with the body's systems.
Highlight Excessive alcohol consumption can lead to severe impairment, including difficulty walking, blurred vision, and in extreme cases, death.
This page continues the discussion on alcohol, focusing on its long-term health effects, and introduces the topic of smoking and its harmful components. It provides crucial information about the harmful effects of tobacco and alcohol on various body systems.
The text outlines the dangers of prolonged alcohol consumption, including
Highlight Long-term alcohol use can cause stomach ulcers, heart disease, and brain and liver damage.
The page explains how the liver processes alcohol and the potential for liver damage (cirrhosis) in heavy drinkers. It also discusses the risks of drinking during pregnancy, including potential harm to the developing fetus.
Example Drinking while pregnant can lead to miscarriage, stillbirth, premature birth, and babies with low birth weight or developmental issues.
The second half of the page introduces the harmful components of cigarette smoke
Vocabulary
- Nicotine An addictive stimulant in tobacco
- Tar A carcinogenic, sticky substance in smoke
- Carbon monoxide A toxic gas that interferes with oxygen transport in the blood
- Particulates Dust particles in tobacco smoke that damage lung cells
This information provides a foundation for understanding how drugs affect the brain and body, particularly focusing on the effects of drug abuse on the human nervous system.
This page focuses on the specific diseases caused by smoking and introduces the classification of drugs based on their effects on the nervous system. It provides a comprehensive list of harmful effects of tobacco on various parts of the body.
The text lists several diseases caused by smoking, including
Highlight Smoking can lead to various types of cancer (lung, throat, mouth), emphysema, heart disease, asthma, bronchitis, and blockages in the arteries.
The page then shifts to categorizing drugs based on their effects on the nervous system
Example Alcohol, cannabis, and heroin are examples of depressant drugs.
Effects Depressants can cause slower information processing, distorted vision, and feelings of illness.
Example Caffeine, cocaine, and ecstasy are examples of stimulant drugs.
This classification helps in understanding how drugs affect the brain and provides insight into the drugs that affect the central nervous system.
This final page concludes the discussion on stimulant drugs and provides a comprehensive overview of the health impacts of smoking. It offers a visual representation of the harmful effects of tobacco on various body parts.
The text lists the effects of stimulant drugs
Effects Stimulants can cause feelings of energy, insomnia, and headaches.
The page then presents a detailed illustration of the body, highlighting the numerous health problems caused by smoking
Highlight Smoking affects multiple body systems, causing issues such as
- Liver cancer
- Dental hygiene problems
- Menstrual issues
- Various types of cancer (mouth, lip, throat, cervical, stomach, kidney)
- Facial wrinkles
- Heart disease
- Asthma
The illustration emphasizes the widespread and severe effects of smoking on the body, serving as a powerful visual representation of the harmful effects of tobacco in points.
Quote "SMOKING KILLS - stop today and make a difference."
This concluding message reinforces the importance of quitting smoking and the immediate benefits of doing so, addressing the concept of immediate effects of smoking cessation.
This page introduces the concept of drugs and their impact on the human body, particularly focusing on the central nervous system. It provides a foundation for understanding the difference between medicinal and recreational drug use, as well as the concepts of addiction and tolerance.
Definition A drug is any chemical substance that affects the central nervous system.
The page distinguishes between medicinal drugs, which are prescribed by doctors for health benefits, and recreational drugs, which are taken for enjoyment or relaxation but often lack health benefits and can be harmful.
Highlight Recreational drugs can lead to addiction and dependency, causing withdrawal symptoms when a person tries to stop using them.
The text explains the process of tolerance, where the body becomes accustomed to the changes caused by a drug, leading to dependency. This can result in addiction, making it difficult for a person to stop using the drug without experiencing unpleasant withdrawal symptoms.
Example Withdrawal symptoms may include headaches, anxiety, and sweating, making it challenging for individuals to quit using drugs.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
