Cigarettes have been a main issue in this country for years. It is currently the leading preventable death in the US. The components that are in cigarettes have led to the cause of several different diseases. It has an effect on three main components in the body. The first part of the body that it affects is the respiratory system. The second part of the body it affects is blood. The last part of the body it affects is the organs in the body. The respiratory system is a vital part of the human body. It allows the body to take oxygen in to the system and allow a person to breath. Cigarettes contain a component called hydrogen cyanide. This has toxic effects on the cilia of the bronchial tubes. The cilia are responsible for filtering and cleaning of the lungs ( There is also tar in cigarette smoke that gets deposited in to the respiratory tract and the lungs which turns them black. The cellular respiration in the respiratory system is also affected. Cellular respiration is what turns oxygen in to carbon monoxide. With the smoking of cigarettes it raises the carbon monoxide in the body and lowers its ability to use the oxygen the body needs. The blood is a vital fluid of the body. Cigarettes have caused a direct problem with the blood which causes several diseases. Oxygen that the body needs is transported in by hemoglobin. When smoke is inhaled it brings in a level of carbon monoxide that is even higher that what cars output. With this level of carbon monoxide it attaches to the hemoglobin almost 200 times faster that oxygen can. This reduces the amount of blood that can be carried around in the body. This makes it so that the brain receives lower oxygen levels and effects the functions that brain can do. Smoking cigarettes has a devastating effect on the organs in the body. The nicotine that is in cigarettes reaches the brain in seconds once it is inhaled. This stimulates the brain cells and then blocks the nerves impulse. Nicotine also causes accelerated heart rate, the contracting and hardening of the arteries. This has the heart pumping but receiving less blood. Carbon monoxide and nicotine both appear to play a part in accelerating the deposition of cholesterol in the inner lining of arteries which over many years leads to arteriosclerosis, a kind of hardening and furring up of arteries which reduces blood flow ( Cigarette smoke causes damage to the phagocytic cells in respiratory epithelium. The main job of these cells is to help rid the lungs of foreign particles and bacteria ( With all the damaging effects that smoking cigarettes people have started smoking electronic cigarettes. It has shown that smoking smokeless cigarettes does have fewer effects on the body than normal ones. It still contains nicotine that can still do damage but what it is missing thousands of other chemicals that normal cigarettes carry in them.
In Conclusion there is nothing good about cigarettes accepted the mental belief that it calls down stress. It has devastating effects on the blood. By causing a raise of carbon monoxide in the body and lowering the blood levels that pass through the heart and brain. The poisons that come from cigarettes reaches the body’s organs causing sever types of diseases. It lowers the blood levels that reach the heart and brain. Smoking leaves tar deposits on the lungs. It destroys the phagocytic cells which in turn lowers the body’s ability to rid the lungs of foreign particles and bacteria. With all the negatives that smoking brings is it really worth the little stress relief it brings. Doesn’t look like it to me.

China’s capital markets do not have a long history. After the civil war in 1949, mainland China had a stock exchange market called the “Tianjin” Stock exchange market. However, the market was shut down in 1952 because of political acts that targeted capital markets and capitalists. After that date, the capital market remained close until the “opening up” policy set in. At that point, the stock markets reopen in the early 90s (Shanghai Stock Exchange and Shenzhen Stock exchange). China’s capital markets are comprised of the stock and bond markets, securities investment funds, and futures. The stock market can be divided in 3 categories, the A-shares, B-shares, and the H-shares. The......

Electronic Cigarettes

...Electronic Cigarettes; The New, Legal Way to Pollute the Body Over the last 10 years, a new craze has taken effect over the world. Electronic cigarettes or E-Cigs, have become popular among all generations. The question for the reader is simple. Is this alternative form of nicotine dependence healthy, or is society setting itself up for a big health shock in the upcoming years? “Many anti-smoking advocates have argued that electronic cigarettes don’t help smokers quit but merely prolong their addiction to nicotine. In other words, the hundreds of thousands of electronic cigarette users in the United States are smokers who, if only they stopped using e-cigarettes, would successfully quit smoking” (Siegel, 2013). Although the issue of E-Cigs is not a burning issue at this moment, imagine what happens in five to ten years if users of E-Cigs are told that the activity they have been participating in is causing many of the ailments that could arise due to the use of E-Cigs in their infancy. The makers of E-Cigs will be sued, the Federal Government will impose fines, and the cool factor will take a big hit. It is almost insulting to societies intelligence to use the description “cool factor.” Moreover, if the reader is fortunate enough to remember the time when regular cigarettes were sold by actors and cartoon characters among other notable figures, then “cool factor” description definitely makes sense. This is a statement......

What Will Happen to the English Language in the Future?

...What will happen to the English language in the future? I haven’t got the slightest idea. Or rather, I probably do, once I have gotten around to thinking properly about it – which should be shortly. If only I were to decide, I would keep the English language ”locked” in a sort of impregnable cell (figuratively of course). When I say “impregnable cell”, what I mean is for the language not to be… tainted – I know that this is a very strong word – by the majority of the youth and their slang. I realise that I might be going out of my depth, so let me try to save myself. Of course the English language would never have come to where it is right now without slang, one can have too much of a good thing. I know this is a horrible example but bear with me, I can’t think of anything else for the time being, but just as too much chemotherapy can kill a cancer patient (and a non-cancer patient, for that matter), so can too much slang butcher a language when applied too fast. You need only look around on the internet to see the erosion that has already happened to the language. I stand by my previous choice of words, as this quick development, in some instances, has rendered the language unrecognisable to the point of it being almost physically painful to (try to) read, e.g. “ayo boi u a hoe i onno y u think errone want dat tiny mean coz ain’t no one duz” (link:, or “Goin 2 my bbies......

What Happens During the Trial

...What Happens During the Trial Events in a trial usually happen in a particular order, though the order may be changed by the judge. The usual order of events is set out below. Step 1: Selection of the Jury. Step 2: Opening Statements. The lawyers for each side will discuss their views of the case that you are to hear and will also present a general picture of what they intend to prove about the case. What the lawyers say in their opening statements is not evidence and, therefore, does not help prove their cases. Step 3: Presentation of Evidence. All parties are entitled to present evidence. The testimony of witnesses who testify at trial is evidence. Evidence may also take the form of physical exhibits, such as a gun or a photograph. On occasion, the written testimony of people not able to attend the trial may also be evidence in the cases you will hear. Many things you will see and hear during the trial are not evidence. For example, what the lawyers say in their opening and closing statements is not evidence. Physical exhibits offered by the lawyers, but not admitted by the judge, are also to be disregarded, as is testimony that the judge orders stricken off the record. Many times during the trial the lawyers may make OBJECTIONS to evidence presented by the other side or to questions asked by the other lawyer. Lawyers are allowed to object to these things when they consider them improper under the laws of evidence. It is up to the judge to......

What Part of the Human Body Is Most Sensitive

...Nathan Coulson What part of the body is most accurate for testing the temperature of a baby's bath water? Your hands are very unreliable at measuring temperature, one reason is because you can become used to extreme temperatures on your hands more readily than other parts of your body. For example, when you first put your hand in water it might feel very hot or very cold, but then as you keep your hand under water, you get used to it, and the water begins to feel more moderate than it really is. This is a very bad thing if you are trying to avoid scalding your baby! Scientists and doctors have proven that the elbow is the most reliable to test your babies bath water because the skin cells on the end of the elbow are more sensitive than any other part of the skin. If you test your baby’s bath with the end of your elbow you are less likely to scald them. What's the structure of the skin? The skin is the largest organ in the body. It has three main layers, the epidermis, the dermis and the subcutaneous layers. The epidermis is an elastic layer on the outside that is continually being regenerated. The dermis is the inner layer that includes the following Epidermis Dermis sweat glands- they produce sweat that travels through the sweat ducts Hair follies- are pits where hair grows. Hairs also play a part in temperature regulation. Source A Subcutaneous layer The subcutaneous layer under the dermis is made up of connective tissue and fat (a......

Cigarettes Are Bad

...Cigarettes Are Bad In today’s world you see cigarettes almost everywhere. There are cigarette breaks at work, and people saying “Man I really need a cigarette after that.” This is great for the big tobacco companies, but not for the cigarette smokers themselves. More people become smokers every day, which means more and more people die each year from smoking cigarettes. Smoking can cause multiple different cancers. Smoking also increases heart rate and blood pressure, and strains the heart, which can cause a heart attack or stroke. Tar build up can also occur and it rips through your lungs like soot in a chimney, and can cause lung cancer. Smoking can also cause many diseases including emphysema, bronchitis, etc. Some people today are trying to find ways to stop smoking. Some ways include patches, gum, and medicines. Sure, scientists have made an impact on spreading the cons of smoking, but each day someone continues to light up, and each day someone new dies from long term smoking. Sarah A.

What Happens When You Remove Soda from School Vending Machines?

...What happens when you remove soda from school vending machines? Sugary soda has been cited as a major cause in the obesity and the associated soaring rates of diabetes 2. Yet a lot of people, including young people, continue to drink sugary soda often. Banning vending machines from schools may not be enough to reduce soda and fast food consumption among students, according to a recent study. A recent study from the University of Illinois at Chicago found that taking soda away from school vending machines could actually have an adverse effect. Even though it is an action intended to make students healthier, it is not enough of an impactful change, the research found. Interestingly enough, students who did not have access to buy soda at school were more likely to drink at least one soda per day. The study found that 23 percent of teens drank at least one soda per day if they had access to vending machines during the school day, compared to 28 percent who did not have access. Showing a similar effect, students were more likely to eat fast food when vending machines were removed from schools. However, these differences were only observed in states where soda was taxed less or students were able to buy soda from the school cafeteria or the school store. The study´s lead author, Daniel Taber, explains, “There may be unintended effects if you only make small-scale changes. When more comprehensive changes were implemented, there were no unintended effects” The......

Cigarette Smoke

...Sweitzer Composition ll Dr. Alex Morris Proposal Essay Cigarette Smoke It is obvious to all of us that tobacco is extremely harmful. Growing up in the culture that we do, the dangerous effects of tobacco are commonly known. Even with all of these warning signs, tobacco use is still extremely common around the world. Leah Diplacido a Ph.D. with the National Cancer Institute (NCI) reports that “438,000 deaths are attributed to cigarette smoking each year: an additional 38,000 deaths are caused by second hand smoke” (DiPlacido 1). This stat makes tobacco the number one preventable cause of death in the United States. Throughout my paper I am going to examine the effects tobacco has on the individual, the effects of second hand smoke, and discuss how quitting may be difficult. Following my examination of tobaccos dangers I will explain a solution that will help limit tobacco users as well give aid for those who are trying to quit the use of tobacco. We all know that tobacco smoke contains chemicals but do we know what these chemicals are and what they can do? The one chemical that people are familiar with is Nicotine. Nicotine is an extremely addictive ingredient of cigarettes. Nicotine plays the part of getting users “hooked”. Although nicotine is a dangerous chemical used in cigarettes there are a number of other chemicals to watch out for. The American Lung Association concluded, “Cigarette smoke contains over 7,000 chemicals, 69 of which are known to......

What Happened to Oliver Cromwell’s Body?

...What Happened to Oliver Cromwell’s Body? Bernice D. Abrams World Civ. 102 Fall I 2008 What Happened to Oliver Cromwell’s Body? Oliver Cromwell was born on April 25, 1599, in Huntingdon, near Cambridge. His father Robert was the younger son of a Knight, which in those days meant that he had very little property. Cromwell grew up in genteel poverty; not quite a member of the nobility, yet not a commoner either. In 1620 he married Elizabeth Boucher. For the early part of his adult life, he scraped along, barely making ends meet on the scraps he had inherited from his father. Then in 1630 the failure of his business caused him to move to St. Ives and begin again as a yeoman farmer. However in 1637 he inherited a modest income and property when his mother’s brother died without heirs. Despite his impoverished circumstances, he had many opportunities to interact with powerful figures at court. His grandfather lived in state at his house outside Huntingdon, where he frequently entertained royalty and court officials. Through his wife’s father, Sir James Bourchier, he was brought into contact with London merchants and leading Puritan figures. In 1630, he suffered what we would today term a mental breakdown. At the same time he under went a powerful religious conversion to the Puritan cause. He afterwards said that he felt as though he was waiting for God to give him a mission. In the meantime, he was elected as a Member of Parliament for......

What Are Electronic Cigarettes?

...I was recently asked to write about electronic cigarettes; at first I was completely confused – I never heard about electronic cigarettes before. However, after a bit of research, I came away quite intrigued by this relatively new product that is taking the industry by storm. So first – what is electronic cigarette? I was amazed to find that electronic cigarettes have been around for a few years now, but it hasn’t been until recently that they have really begun to become prominent in the marketplace. Electronic cigarettes serve two distinct purposes – one, they can provide smokers with a healthier alternative to traditional cigarettes, and two, they can be used as a method to stop smoking altogether. Electronic cigarettes have the appearance of a real cigarette, but instead it is a canister with a nicotine cartridge inside. They do not contain any tobacco and do not have any of the unpleasant toxins and carcinogens that are found in conventional cigarettes. An electronic cigarette (or “e-cig”) has an atomizer inside that is triggered by the user inhaling through the mouthpiece. This atomizer activates the nicotine cartridge and a vapor is inhaled. On the opposite end, the e-cig gives off an orange glow, as if the cigarette were “lit.” The great thing about e-cigs is that the act of smoking a real cigarette is replicated – the user puts it to their mouth, inhales and exhales as if they were smoking a real cigarette. For those who use e-cigs as a means to quit......
