http://www.nucleushealth.com – Millions of people die each year from smoking. This 3D medical animation is part of an anti-smoking campaign ad, showing how smoking causes normal alveolar sacs to become enlarged and thinned over time from emphysema. Because the alveoli cannot contract, air is trapped in the lungs and the smoker cannot breathe out effectively.

Each cigarette puff contains a blend of approximately 6,000 chemicals; when you inhale, the smoke hits your lungs rapidly, and the blood that is subsequently transmitted to the rest of your body carries these deadly compounds. Smoking tobacco releases carbon monoxide, a dangerous gas that displaces oxygen in your blood and deprives your organs of the oxygen they require. #shorts #animation #cigarette #lungs #health #smoking

Did you know that smokers are twice as likely to have a heart attack? And that one in two smokers will die from a smoking-related disease.
In fact all of these things are negatively affected by smoking… pretty much every organ in your body!

We all know that smoking is bad, but do you know why?
That’s what we’re going to discover in this video.
When you pass someone smoking, does it make you cough or your chest feel tight?
Perhaps you thought it was the smell? It’s actually because you’re inhaling dangerous substances into your body.
Nicotine is a toxin that stimulates your body to produce adrenaline. This increases your heart rate and raises your blood pressure, thus making your heart work harder. It is also addictive, which is why it’s very difficult for smokers to quit.
Tar contains over a thousand chemicals. It forms a tacky brown or yellow residue – which is why some smokers have stained teeth. And if you could see them – stained lungs too.
Some of the chemicals in tar are carcinogens – so they cause cancer, making lung, mouth and throat cancers more common in smokers.
The last culprit you need to know about is Carbon Monoxide. It is an odourless, colourless and extremely poisonous gas. The carbon monoxide permanently binds to haemoglobin in your blood, blocking oxygen from binding.
So oxygen can’t be transported around the body and used for respiration, causing shortness of breath and fatigue. Your heart once more has to beat even faster to supply the body with the oxygen it needs.
Let’s now look at some diseases caused by smoking…
Emphysema is when the tiny structures in your lungs called alveoli, break down.
As alveoli are responsible for gas exchange, this is not good news. The inhaled smoke causes the walls of the alveoli to weaken and decrease in surface area, making gas exchange less efficient. Unsurprisingly, breathing becomes much harder and smokers are much more at risk of coughs and chest infections.
Smoking also causes the cilia in the lungs to become irritated, and produce excess mucus.
So that’s the lungs. And we saw earlier that nicotine and carbon monoxide make the heart work much harder.
Now the blood vessels.
Plaque building up in the coronary arteries, so the ones that transport oxygen rich blood around the heart, can over time cause a blood clot to form, which cuts off some of the heart muscle and causes it to die. This is the most common cause of heart attacks.
So we’ve seen that smoking increases your risk of heart, lung, kidney disease, strokes and cancers.
Smoking can also make your bones more brittle and so more likely to break. And also it can greatly reduce fertility in both men and women.
So, now you know some of the harmful effects smoking has on your body and why we’re told not to do it. But the good news… once you stop smoking, your health improves and your body will begin to recover. It’s never too late to give up!

Transcript:
Every time you smoke a cigarette, toxic gases pass into your lungs, then into your bloodstream, where they spread to every organ in your body. A cigarette is made using the tobacco leaf, which contains nicotine and a variety of other compounds. As the tobacco and compounds burn, they release thousands of dangerous chemicals, including over forty known to cause cancer. Cigarette smoke contains the poisonous gases carbon monoxide and nitrogen oxide, as well as trace amounts of cancer-causing radioactive particles. All forms of tobacco are dangerous, including cigars, pipes, and smokeless tobacco, such as chewing tobacco and snuff.
Nicotine is an addictive chemical in tobacco. Smoking causes death. People who smoke typically die at an earlier age than non-smokers. In fact, 1 of every 5 deaths in the United States is linked to cigarette smoking.
If you smoke, your risk for major health problems increases dramatically, including: heart disease, heart attack, stroke, lung cancer, and death from chronic obstructive pulmonary disease.
Smoking causes cardiovascular disease.
When nicotine flows through your adrenal glands, it stimulates the release of epinephrine, a hormone that raises your blood pressure. In addition, nicotine and carbon monoxide can damage the lining of the inner walls in your arteries. Fatty deposits, called plaque, can build up at these injury sites and become large enough to narrow the arteries and severely reduce blood flow, resulting in a condition called atherosclerosis. In coronary artery disease, atherosclerosis narrows the arteries that supply the heart, which reduces the supply of oxygen to your heart muscle, increasing your risk for a heart attack. Smoking also raises your risk for blood clots because it causes platelets in your blood to clump together. Smoking increases your risk for peripheral vascular disease, in which atherosclerotic plaques block the large arteries in your arms and legs. Smoking can also cause an abdominal aortic aneurysm, which is a swelling or weakening of your aorta where it runs through your abdomen.
Smoking damages two main parts of your lungs: your airways, also called bronchial tubes, and small air sacs called alveoli. Cigarette smoke irritates the lining of your bronchial tubes, causing them to swell and make mucus. Cigarette smoke also slows the movement of your cilia, causing some of the smoke and mucus to stay in your lungs. While you are sleeping, some of the cilia recover and start pushing more pollutants and mucus out of your lungs. When you wake up, your body attempts to expel this material by coughing repeatedly, a condition known as smoker’s cough. Over time, chronic bronchitis develops as your cilia stop working, your airways become clogged with scars and mucus, and breathing becomes difficult.
Your lungs are now more vulnerable to further disease. Cigarette smoke also damages your alveoli, making it harder for oxygen and carbon dioxide to exchange with your blood. Over time, so little oxygen can reach your blood that you may develop emphysema, a condition in which you must gasp for every breath and wear an oxygen tube under your nose in order to breathe.
Chronic bronchitis and emphysema are collectively called chronic obstructive pulmonary disease, or COPD. COPD is a gradual loss of the ability to breathe for which there is no cure.
Cigarette smoke contains at least 40 cancer-causing substances, called carcinogens, including cyanide, formaldehyde, benzene, and ammonia. In your body, healthy cells grow, make new cells, then die. Genetic material inside each cell, called DNA, directs this process. If you smoke, toxic chemicals can damage the DNA in your healthy cells. As a result, your damaged cells create new unhealthy cells, which grow out of control and may spread to other parts of your body. Cigarettes can cause cancer in other parts of your body, such as: in the blood and bone marrow, mouth, larynx, throat, esophagus, stomach, pancreas, kidney, bladder, uterus, and cervix.
Smoking can cause infertility in both men and women. If a woman is pregnant and smokes during pregnancy, she exposes her baby to the cigarette’s poisonous chemicals, causing a greater risk of: low birth weight, miscarriage, preterm delivery, stillbirth, infant death, and sudden infant death syndrome. Smoking is also dangerous if a mother is breastfeeding. Nicotine passes to the baby through breast milk, and can cause restlessness, rapid heartbeat, vomiting, interrupted sleep, or diarrhea.
Other health effects of smoking include: low bone density and increased risk for hip fracture among women; gum disease, often leading to tooth loss and surgery; immune system dysfunction and delayed wound healing; and sexual impotence in men.
Smoking can cause lung cancer, but there are other types of cancer related to smoking traditional cigarettes.
Michael Hernandez, Critical Care & Pulmonary Medicine Physician at South Miami Hospital, says there are others cancers associated with tobacco, like head, neck, mouth and esophageal cancer.
Smoking is bad for your health and you should avoid it, because it also causes coronary diseases. Video Rating: / 5
