KS3 Science Quiz - Health 01 (Questions)

This KS3 Science quiz takes a look at health. In order to keep as healthy as possible, you need to eat a balanced diet. A balanced diet supplies your body with the nutrients that it needs to work properly. More importantly, it supplies the nutrients in the right quantities too. Too much or too little of one or more nutrients can affect your health in a negative way. As an example, take vitamin C - too little of this important vitamin can lead to the disease called scurvy and taking large doses of vitamin C can lead to diarrhoea, vomiting, headaches, insomnia and kidney stones (plus a few other things too).

Drugs are chemical substances that affect our bodies. Some are beneficial when used correctly e.g. medicines but there are also 'recreational' drugs. These are not medicines and are taken by people in order to have a certain effect on the body like having hallucinations or to stay awake longer. Some recreational drugs are legal, the most common one is probably alcohol. Both recreational drugs and medicines, if taken in large doses or taken frequently and over a long period of time, can permanently damage your health.

KS3 Science Quiz - Health 01 (Answers)
1. Which of the following is caused by smoking?
[ ] Lung cancer
[ ] Bronchitis
[ ] Emphysema
[x] All of the above
The chemicals from smoking get into your bloodstream and can affect the health of virtually any organ in the body
2. Which poisonous gas is present in smoker's smoke?
[ ] Carbon dioxide
[x] Carbon monoxide
[ ] Hydrogen
[ ] Sulfur dioxide
Tobacco smoke also contains nicotine, an addictive drug as well as tar and loads of other chemicals that should not be inside the body
3. Which of the following organs is MOST damaged by smoking?
[ ] Brain
[ ] Heart
[ ] Liver
[x] Lungs
The respiratory system is the first point of contact with the smoke
4. Passive smoking is:
[x] Breathing in smoke that others exhale
[ ] Only smoking occassionally
[ ] Smoking quietly
[ ] Smoking without inhaling smoke
This can be just as harmful as inhaling smoke directly from a cigarette, cigar etc. Possibly worse as it has not passed through any kind of filter
5. Which of the following can be caused by alcohol?
[x] Brain damage
[ ] Bronchitis
[ ] Emphysema
[ ] Lung cancer
Even small amounts of alcohol can kill off brain cells. Drinking more than the recommended maximum amount of alcohol regularly can lead to memory problems as the brain cells die
6. Alcohol is an example of:
[x] A depressant
[ ] A pain killer
[ ] A stimulant
[ ] An hallucinogen
A depressant slows down brain function and affects the way your nerves communicate messages through your body. That is why people who have consumed a large quantity of alcohol have slurred speech, cannot think properly and fall over as the nervous system can no longer function properly
7. Which two of the following organs can be damaged by drinking too much alcohol?
[ ] Brain and heart
[x] Brain and liver
[ ] Liver and pancreas
[ ] Stomach and kidney
Alcohol kills brain cells and causes a disease called cirrhosis of the liver. Both of these prevent these important organs from working correctly
8. Ecstasy is an example of:
[ ] An antidepressant
[ ] A pain killer
[x] A stimulant
[ ] An antihistamine
Ecstasy is an addictive drug that is also hallucinogenic. It can lead to depression, anxiety, memory loss and insomnia. There have also been cases of people dying after taking ecstasy
9. Which one of the following is NOT involved in solvent abuse?
[ ] Glue
[ ] Paint
[x] Vodka
[ ] White spirit
Inhaling solvents can permanently damage organs such as the brain and lungs
10. Which one of the following is NOT an effect of inhaling solvent fumes?
[ ] Makes you have hallucinations
[x] Makes you hyperactive
[ ] Makes you light headed
[ ] Makes you sleepy
Solvents, like alcohol, are depressants and slow down the messages passing between your nerve cells
