The Health Effects of Tobacco Hockett 2016 Learning Objectives ● identify various forms of tobacco and the addictive substances in tobacco products; ● assess the hazardous effects nicotine has on the cardiovascular and respiratory system. ● describe harmful substances in tobacco products and smoke that result in serious illness and disease; and ● analyze the impact of secondhand smoke on individuals. Unit Vocabulary asthma carbon monoxide carcinogens nicotine chronic bronchitis secondhand smoke chronic obstructive pulmonary disease emphysema tar leukoplakia tobacco smokeless tobacco Tobacco Products Tobacco is a plant product used for the production of tobacco related products. - Cigarettes & chewing tobacco. Nicotine is the addictive, toxic substance that gives tobacco products their addictive quality. cigarettes, pipes,hookahs,smokeless tobacco, electronic cigarettes, Health Risks of Using Tobacco over time Tobacco and Your Body On average, long-term smokers die 13 to 15 years earlier than non smokers. Tobacco use increases a person's risk for developing number of major health problems, including cancers of the mouth, pharynx, esophagus,lungs and bladder. coronary heart disease stroke, bronchitis, and emphysema and respiratory infections. Tobacco and Your body The Surgeon General recently issued out a report on smoking and it linked smoking with numerous additional illness. higher risk for developing diabetes, liver cancers, vision loss, tuberculosis, and arthritis. Tobacco products and smoke contain thousands of chemicals and substances that are harmful. Ingredients in Tobacco products Nicotine Carbon Monoxide Tar Carcinogens The Cardiovascular System The cardiovascular system includes the heart and blood transportations. Smokers have a higher risk of developing heart disease and high blood pressure than non smokers. Smokers are also twice as likely to die from heart attack as nonsmokers. This is due to nicotine and carbon monoxide in the blood system. Nicotine Nicotine enters the bloodstream. Its presence triggers the release of the hormone adrenaline, a stimulant. Adrenaline increases the heart rate , breathing rate, and blood pressure. The increase in speed and pressure of blood flow in the body makes the heart work harder to pump blood faster around the body. Nicotine also causes the blood vessels to constrict. Making it harder for the blood to flow through the body. Nicotine Continued Blood flow in body increases - blood vessels narrow. Because blood vessels narrow it makes it harder for fat and plaque to pass through. (cholesterol). Overtime the build up leads to a heart attack or stroke. Carbon Monoxide Cigarettes Contain high levels of carbon monoxide. Carbon Monoxide - a poisonous gas found in cigarette smoke; negatively affects cells’ ability to carry oxygen. When inhaled, carbon monoxide interferes with the ability of blood cells to carry oxygen. This reduces the amount of oxygen in the blood and the amount of oxygen that it reaches the heart. The Respiratory System The respiratory system’s primary function is to enable breathing. Nose takes in air - bronchial tubes - lungs - are lined with tissue containing fine, hair like projections called cilia. The cilia trap and move foreign particles out of the respiratory tract. The respiratory System Continued When a person smokes, damage is done to the respiratory system that makes breathing more difficult. The burning of tobacco produces a residue known as Tar. -Small, thick, sticky particles and can build in lungs over time. Disrupts the cilia to effectively clear the lungs of foreign particles. Starts chronic respiratory disease and asthma. COPD Chronic Obstructive Pulmonary Disease - a group of diseases that cause difficulty breathing; includes chronic bronchitis and emphysema. Group 1 - Chronic Bronchitis Group 2 - Emphysema Group 3 - Asthma Group 4 - Other Illnesses ( How does smoking make people more susceptible to germs, ulcers, fertility problems. ect) Define it… what parts of the respiratory system are affected.... relevant statistics... Lung Cancer and Cancers Lung Cancer occurs when abnormal cells in one or both lungs grow rapidly and form a mass of cells which is called a tumor. The growth usually happens in the cell that line the air passages. As tumors grow, they interfere with the lungs’ ability to transport oxygen to the bloodstream. Tumors can also spread from the lungs to other parts of the body. Carcinogen - substances that causes cancers. Your appearance is important. Your Appearance Tobacco has numerous negative internal effects, but it also has negative external effects. People who smoke for at least 10 years show more wrinkles in their skin, because nicotine and tobacco causes blood vessels to get smaller making it difficult for oxygen and nutrients to reach the skin. Stains teeth, brittle nails, and thin hair. Smokeless Tobacco Smokeless Tobacco Smokeless Tobacco - a tobacco related product that does not require burning; includes chewing tobacco and electronic cigarettes. Finely cut tobacco or powdered tobacco that is inhaled or placed between the cheek and gums. Dissolvable tobacco is taken in the form of flavored mouth drops or strips. Less likely to develop lung problems but you are more likely to develop leukoplakia - a condition characterized by white, leathery spots inside the mouth Impact of Secondhand Smoke Secondhand smoke - tobacco smoke in the environment that may affect a person even if he or she does not smoke. Pregnant Women who are exposed to nicotine is particularly hazardous to a developing fetus. Passes through the placenta and into the fetus increasing the HR and reduces the amount of oxygen to the fetus. Children develop respiratory problems Review Questions 1. 2. 3. 4. 5. 6. Define adrenaline. How does nicotine affects adrenaline and the body. Explain how nicotine affects the blood vessels. How does this impact on blood vessels cause smokers to be twice as likely as nonsmokers to die from a heart attack. Describe carbon monoxide and the effects it has on the cardiovascular system. Describe how tar accumulates in the respiratory system and how it affects the lungs. How does smoking or breathing in cigarette smoke impact people with asthma. Why do smokers have a higher risk of cancer that non smokers? Review Answers 1. 2. 3. 4. 5. 6. Adrenaline is a hormone that increases heart rate, breathing, and blood pressure; these increases make the heart work harder to pump blood. Nicotine constricts blood vessels and makes it easier for fatty substances to build up; these buildups restrict blood transportation and increase risk for heart attack. Carbon monoxide interferes with the ability of the cells to carry oxygen; as a result, less oxygen reaches the heart. Tar builds up in the lungs and hinders cilia from cleaning the lungs of foreign objects. Tobacco smoke irritates airway linings, which can lead to an asthma attack. Tobacco smoke contains carcinogens, which are cancer causing agents.
