How dose Smoking affects your Lungs ks3

In this article, we will discuss How dose Smoking affects your Lungs ks3. Each organ in your body plays an important role in keeping your body healthy. If you have healthy lungs, you probably don’t think much about them. Damage to your lungs, however, can quickly cause a noticeable difference in your ability to breathe easily.

The primary role of the lungs is to deliver oxygen-rich blood throughout the body. You breathe in air and breathe out carbon dioxide as waste exhaling. No tobacco product is safe. However, combustible products—those you burn to smoke—are exceptionally harmful to the lungs.

 Does Smoking cause your lungs to bleed?

Smoking is more commonly associated with lung diseases such as lung cancer but is also linked to heart disease. Smoking can increase a person’s risk of blood clots resulting in a stroke. According to the American Heart Association, a smoker is likely to die a decade sooner than a nonsmoker. 

It all comes down to chemicals and toxicity. Nearly 600 ingredients are found in cigarettes, and many chemicals in cigarettes and cigarette smoke cause cancer. Some are poisonous and extremely toxic.

Smoking changes the surface of blood platelets, making it easier for them to clump together. Damage to the lining of blood vessel walls is also associated with Smoking, which increases the potential for clots to form.

According to the National Heart, Lung, and Blood Institute, Smoking has a serious and detrimental impact on blood vessels and the heart. It’s the chemicals found in tobacco smoke that damage blood cells. Smoking can also damage the heart muscle and blood vessel structure and function.

Any damage to blood vessels increases a person’s risk of atherosclerosis – a narrowing of the arteries caused by plaque buildup. Most associate atherosclerosis with high cholesterol levels or obesity, but the same damage potential is present with the over 5,000 chemicals in cigarette smoke.

Smoking is also a major contributing factor to peripheral artery disease (PAD) development. This condition contributes to plaque buildup in arteries that carry blood to vital organs and areas of the body, including the heart, the lungs, and the brain.

Individuals should be aware that secondhand smoke carries the same dangers to individuals as it does to the person smoking the cigarette. Research has shown that secondhand smoke can increase blood pressure, damage the muscular heart tissues, and lower levels of high-density lipoprotein or HDL cholesterol, commonly nicknamed the “good” cholesterol.

How does quitting Smoking help your body

The health benefits of quitting smoking can help most of your body’s major parts: your brain to your DNA.


Broken Addiction Cycle

Quitting smoking can re-wire your brain and help break the cycle of addiction. The large number of nicotine receptors in your brain will return to normal levels after about a month of being quit.

Head and Face

Sharp Hearing

Quitting Smoking will keep your hearing sharp. Remember, even mild hearing loss can cause problems (like not hearing directions correctly and doing a task wrong).

Clear Skin

Quitting Smoking is better than anti-ageing lotion. Quitting can help clear blemishes and protect your skin from premature ageing and wrinkling.


Decreased Heart Risks

Smoking is the leading cause of heart attacks and heart disease. But many of these heart risks can be reversed simply by quitting Smoking. Quitting can lower your blood pressure and heart rate almost immediately. Your risk of a heart attack declines within 24 hours.


Stop Lung Damage

Scarring of the lungs is not reversible. That is why it is important to quit Smoking before damaging your lungs permanently. Within two weeks of quitting, you might notice it’s easier to walk up the stairs because you may be less short of breath. Don’t wait until later; quit today!


Lower Cancer Risk

Quitting Smoking will prevent new DNA damage from happening and can even help repair the damage already done. Quitting smoking immediately is the best way to lower your cancer risk.

Stomach and Hormones

Smaller Belly

Quitting smoking will reduce your belly fat and lower your risk of diabetes. If you already have diabetes, quitting can help you check your blood sugar levels.

Normal Estrogen Levels

If you’re a woman, your estrogen levels will gradually return to normal after you quit smoking. And if you hope to have children someday, quitting Smoking right now will increase your chances of a healthy pregnancy.

What Chemicals Are In Cigarette Smoke?

Experts say that cigarette smoke contains over 4,000 different compounds. Many of them are toxic (poisonous) and can damage our cells; many are carcinogenic (cause cancer). If you’ve ever wondered exactly what you might be breathing in when you inhale cigarette smoke, this list is a real eye-opener.

We’ve listed information on a few compounds found in tobacco and cigarette smoke. Note that the most abundant ones, tar, nicotine and carbon monoxide, are at the bottom of this list:

  • Acetaldehyde – this chemical is used in resins and glues. It is believed to be a carcinogen. Experts say it is likely to facilitate the absorption of another dangerous chemical into the bronchial tubes.
  • Acetone – this chemical is used in solvents. It irritates the eyes, nose and throat. Long-term exposure can damage the liver and kidneys.
  • Acrolein – is commonly used in herbicides and polyester resins. It is also used in chemical warfare. Acrolein is an ingredient in tear gas. It is very poisonous and irritates the eyes and upper respiratory tract.
  • Ammonia – is known to cause asthma and raise blood pressure. Ammonia is used in cleaners.
  • Benzene – used in gasoline, causes several cancers, including leukaemia
  • Benzo[a]pyrene – this chemical is found in coal tar pitch and creosote. It is a known carcinogen, especially for lung and skin cancers. It can also undermine human fertility.
  • 1,3-Butadiene – it is used in latex, rubber and neoprene products. Experts believe it is most likely a carcinogen.
  • Butyraldehyde – this chemical affects the lining of the lungs and nose. It is used in solvents and resins. It is a powerful inhalation irritant.
  • Cadmium – a known carcinogen. It damages the brain, kidneys and liver. Cadmium is used in non-corrosive metal coatings, storage batteries, pigments, and bearings.
  • Catechol – elevates blood pressure and irritates the upper respiratory tract. It can also cause dermatitis. Catechol is used as an antioxidant in oils, inks and dyes.
  • Chromium – is known to cause lung cancer. It is used in wood treatment, wood preservatives, metal plating and alloys. Those involved in welding have the greatest risk of exposure.
  • Cresol – acute inhalation can cause throat, nasal and upper respiratory irritation. It is used in disinfectants, wood preservatives and solvents.
  • Crotonaldehyde – a warning agent in fuel gasses. Experts say it messes up the human immune system. It can also cause chromosomal changes.
  • Formaldehyde – part of the resin used in foam insulation, plywood, fiberboard and particleboard. It can cause nasal cancer, as well as damage to the digestive system, skin and lungs.
  • Hydrogen Cyanide – some states use this chemical in their gas chambers for executions. It weakens the lungs and causes fatigueheadaches and nausea. It is used in producing acrylic plastics and resins and can also be a fumigant.
  • Hydroquinone – has a detrimental effect on the central nervous system. Also causes eye injuries and skin irritation. It is used in varnishes, motor fuels and paints.
  • Isoprene – similar to 1,3-butadiene. It causes skin, eye and mucous membrane irritation. It is used in rubber.
  • Lead – lead damages the nerves in the brain, kidneys, and human reproductive system. Lead intake can also cause stomach problems and anaemia. It is a known carcinogen and is particularly toxin to children. Lead is used in paint and metal alloys.
  • Methyl Ethyl Ketone (MEK) – depresses the human nervous system and irritates the eyes, nose and throat. MEK is used in solvents.
  • Nickel – a known carcinogen, also causes bronchial asthma and upper respiratory irritation.
  • Nitric Oxide – this is a major contributor to smog and acid rain. It is made by gasoline combustion. Scientists say it is linked to a higher risk of developing Alzheimer’s disease, Parkinson’s disease, Huntington’s, and asthma.
  • NNN, NNK, and NAT – NNN and NNK have known carcinogens, and NAT might be one. The three compounds are unique to tobacco. NNN may also cause reproductive problems. NNK is closely linked to lung cancer risk.
  • Phenol – this highly toxic substance is harmful to the CNS (central nervous system), cardiovascular system, respiratory system, kidneys and liver. It is used in resins in plywood and construction materials.
  • Propionaldehyde – irritates the respiratory system, skin and eyes. It is used as a disinfectant.
  • Pyridine – irritates the eyes and upper respiratory tract. It also causes nervousness, headaches and nausea. Experts say it might cause liver damage. This substance is used in solvents.
  • Quinoline is used to stop corrosion and as a solvent for resins. It is a severe eye irritant that harms the liver and causes genetic mutations. Experts believe it may be a carcinogen.
  • Resorcinol – irritates the eyes and skin. It is used in resins, adhesives (glue) and laminates.
  • Styrene – irritates the eyes, may slow reflexes, and causes headaches. It is linked to a higher risk of leukaemia. This substance is used in fibreglass, pipes, plastic and insulation materials.
  • Toluene – causes confusion, memory loss, nausea, weakness, anorexia, and drunken movements. It is also associated with permanent brain damage. The chemical is used in resins, oils and solvents.
  • Nicotine – is not carcinogenic. However, it is highly addictive. Smokers find it very hard to quit because they are hooked on nicotine. Nicotine is an extremely fast-acting drug. It reaches the brain within 15 seconds of being inhaled. If cigarettes and other tobacco products had no nicotine, the number of people who smoke every day would drop drastically.

What are the consequences of Smoking?

Cigarette smoke has negative consequences for individuals of all ages. Babies born to mothers that smoked during pregnancy may have abnormal lung development. Teens who smoke may develop weaker lungs which never operate at full capacity or develop to their full, adult size.

Additionally, Smoking can destroy the cilia. These tiny hairs in the airway keep dirt and mucus out of your lungs. This may lead to the development of “smoker’s cough,” a chronic cough common for long-term smokers.

Smokers also risk chronic obstructive pulmonary disease (or COPD). 80% of cases of COPD are due to Smoking.  People with COPD have difficulty breathing and eventually die because of the lack of oxygen.

COPD has no cure. Moreover, nearly all lung cancer—the top cause of cancer death— is due to Smoking. Smokers are 20 times more likely to develop lung cancer than nonsmokers. 3  Lung cancer may also lead to other respiratory cancers.

FAQ about how does Smoking affect your lungs ks3

What happens to your body when you quit smoking?

Around 3 days after quitting, most people will experience moodiness and irritability, severe headaches, and cravings as the body readjusts. In as little as 1 month, a person’s lung function begins to improve. As the lungs heal and lung capacity improves, former smokers may notice less coughing and shortness of breath.

How can I clean my lungs from Smoking? 

 Exercise increases the amount of oxygen delivered to cells and tissues throughout your body. Cardiovascular exercises like brisk walking, swimming, running, and cycling are ideal for helping to clear out your lungs after you quit smoking.

Can a smoker’s lungs go back to normal?

Can Lungs Go Back to Normal After Quitting Smoking? Yes, your lungs can go back to normal after quitting Smoking. One large study found that after 20 years of being smoke-free, the risk of COPD drops to the same as if you have never smoked, and after 30 years, the risk of lung cancer also drops to the same risk as nonsmokers.
