Smoking!✨🤮🚬 💨 Flashcards
Who alls health does smoking cigarettes damage?
Smoking cigarettes damages the smoker’s health, and it also damages the health of the people around them, who accidentally breathe in cigarette smoke.
What is nicotine?
Tobacco smoke(and tobacco leaves naturally) contain nicotine.
What does nicotine help with?
Nicotine can help someone to stay alert.
Why do smokers find it hard to stop smoking?
This is because nicotine, found in tobacco smoke, is addictive, which means that it is difficult to manage without it, once you are used to smoking.
How is nicotine harmful for the body?
Nicotine damages the blood vessels in a smokers body by making them narrower, making it harder for blood to get through them. Smokers are more likely than non-smokers to develop heart disease.
What is tar?
Tar is a dark, sticky substance found in tobacco smoke.
How is tar harmful for the body?
Some of the chemicals in tar cause cancer, which happens when cells start dividing out of control and spread to other parts of the body. Smoking increases the risk of getting many different kinds of cancer, including lung cancer.
What is carbon monoxide?
Carbon monoxide is a poisonous gas.
How is carbon monoxide harmful for the body?
When carbon monoxide gets into the body, it combines with haemoglobin inside red blood cells, and stops haemoglobin doing its normal job, which is to combine with oxygen and transport it to all the body cells that need it. So a smoker’s cells don’t get enough oxygen, they can’t carry out enough respiration, so they don’t have enough energy.
What are particulates?
Particulates are tiny particles of carbon and other materials, found in tobacco smoke.
Why are particulates harmful for the body?
Particulates get trapped inside smoker’s lungs, making the walls of alveoli break down. Instead of having millions of tiny alveoli in their lungs, the smoker has a lot of big spaces, which makes it difficult for enough oxygen to get into their blood.
