Cigarette smokers die younger than non-smokers. Smoking affects the respiratory system because it stops the small little hairs in your throat from working as well these small little hairs are called Cilia and are used to push dirt and mucus out of your throat so it can be breathed out or swallowed when reaches top of throat (this is the stuff which makes fingers yellow etc.).Smoking is also known to make alveoli in the lungs a more round shape than small cauliflower shape. This decreases the surface area and results in less oxygen filling lungs again leaving you of breath. It also affects your digestive system and circulatory system because it contains a lot of carbon monoxide which sticks to the hemoglobin in the blood instead of oxygen this means that many organs don't get enough oxygen as they should do so it increases blood pressure so any small amount of oxygen can reach organs anyway. This also means that less oxygen is swapped over in the gas exchange at the lungs which can often leave those who smoke out of breath quickly. Mucus which would also be removed through cilia goes in to blood stream and is deposited in arteries making them very fatty also increasing heart rate. All in all it also increases chances of lung diseases, strokes and heart failure etc. The main cause of lung cancer is smoking tobacco because it is a carcinogen.Long Term effects of tobacco smoke on the Digestive System include: Smokers have been shown to have an increased chance of getting stomach ulcers. Bad breath is always an issue for the smoker. Some recent research has shown that smokers have a much greater chance of having bowel problems. Increases in the chances of cancer of the mouth, esophagus and pancreas.Long Term effects of tobacco smoke on the Circulatory System include: As a smoker you stand a far greater chance of suffering from heart disease and other circulatory problems. In fact, it has been shown that you are up to 5 times more likely to suffer a heart attack. One of the reasons for this rise is that smoking cigarettes leaves deposits of fat and cholesterol on the blood vessels. This in time means that the vessels become thin and hardened. Which leads to lowering of the blood pressure over time. This leads to problems particularly on the organs which really depend on good blood flow the heart and the brain. This decrease in blood flow leads to a greater chance of peripheral vascular disease amongst other things. Raised blood pressure and heart rate. Constriction (tightening) of blood vessels in the skin, resulting in a drop in skin temperature. Less oxygen carried by the blood Stickier blood, which is more prone to clotting. Causes bad chemicals to be taken to your heart. Stickier blood, which is more prone to clotting Damage to the lining of the arteries, which is thought to be a contributing factor to atherosclerosis (the build-up of fatty deposits on the artery walls) Reduced blood flow to extremities like fingers and toes Increased risk of stroke and heart attack due to blockages of the blood supply. Youth smokers experience immediate health effects, such as: more phlegm production and smokers cough, decreased physical fitness, shortness of breath, decreased endurance, more colds and bronchitis, increased heart rate, a slower rate of lung development, allergy flare-ups more colds, flu and pneumonia.The long term effects of tobacco smoke on the respiratory system include: Asthma, Chronic obstructive pulmonary disease, Decreased endurance , Impaired lung functionIncreases respiratory symptoms, Respiratory infections, Mouth cancer, Chronic bronchitisIrritation of the trachea (windpipe) and larynx (voice box). Reduced lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages. Impairment of the lungs clearance system, leading to the build-up of poisonous substances, which results in lung irritation and damage. Increased risk of lung infection and symptoms such as coughing and wheezing. Permanent damage to the air sacs of the lungs.Cancers caused by smoking. Cigarette smoking accounts for at least 30% of all cancer deaths. It is linked with an increased risk of these cancers: Lung Larynx (voice box) Oral cavity (mouth, tongue, and lips) Nose and sinuses Pharynx (throat) Esophagus (tube connecting the throat to the stomach) Stomach Pancreas Cervix

Kidney Bladder Ovary (a type called mucinous ovarian cancer) Colorectal (the colon and/or the rectum) Acute myeloid leukemia
