...of the respiratory system with reference to the pathophysiology. Respiratory or lung diseases are the most rapidly diseases expanding worldwide. Health problems of the lungs or airways make it very difficult to breath. They could be lasting a short amount of time like the common cold or for years. Other allergic diseases, which affect the respiratory system. Respiratory diseases are mostly caused by indoor pollutants. The primary function of the respiratory system is to supply the blood with oxygen. When this fails death is not excluded. Lung diseases occur within the lungs. Some lung and respiratory diseases include asthma, pneumonia tuberculosis and lung cancer. Those will be analyzed in the following essay. [1] Asthma or reactive airway disease is a chronic disorder that results in restricted breathing due to inflammation of the bronchi tubes the main air passages in the lungs. Asthma affects 3-5 % of adults and 7 -10 % of children in the USA. Sever asthma attacks can cause approximately 5000 deaths per year. Three changes occur in the lungs of the people with asthma. First inflammation or swelling where the airway becomes inflamed and produce a mucous. Inflammation then leads to constriction of the muscles around the airways causing the airways to become narrow. This narrowing is also referred to as bronchiole spasm. The third change is increased sensitivity of the airways causing the asthma patient to become overly sensitive to animal dander, pollen, cold air and tobacco...

... Restrictive vs. Obstructive Lung Disease Breath in with the weight of a thousand elephant’s, Heart pounding, feeling all is lost, Breath out with the strength of hundreds, Chest throbbing, Wishing nothing more than for the pain to stop, and both are a wasted effort. Feelings of hopelessness, No one can imagine the suffering you are feeling. This is what people go through everyday with restrictive or obstructive lung disease, while both are different they are very much the same and they are deadly however they are treatable as well as preventable. Restrictive lung disease as known as restrictive ventilator defects is where the disease causes the lung to restrict its expansion which makes it los lung volume. Which in other words the lung its self as lost its ability to expand due to lose of tissue or cell stiffening due to invasive environmental factors. Having a restrictive lung disease can make it very hard to breath and impairs the body’s ability to transfer oxygen into the body’s bloodstream. Without having the proper amount of oxygen in our blood our bodies can begin to shut down. Now obstructive lung disease is the opposite, obstructive lung disease is where the lung cannot exhale all the air in the lungs. This can be cause by damage or narrowing of the airways as well as blocked or inflamed airways. We exhale carbon dioxide and not being able to exhale all the air in the lung can lead to poisoning by carbon dioxide, not by...

...SMOKING KILLS! Contents of a cigarette What are the effects of smoking on the lungs? Lung cancer is the most common form of cancer caused by smoking. More than 80% of cases of lung cancer are due to smoking. Cigarette smoke contains many chemicals that interfere with the body's method of filtering air and cleaning out the lungs. The smoke irritates the lungs and leads to overproduction of mucus. It also paralyses the cilia - tiny hair-like structures that line the airways and clean out dust and dirt. Paralysis of the cilia means mucus and toxic substances accumulate, resulting in congestion of the lungs. This extra mucus means smokers are more likely to suffer from chronic bronchitis and what is known as 'smoker's cough'. Cigarette smoke is one of the best known triggers of asthma. When people suffer from asthma their inflamed air passages, which are very sensitive, narrow when exposed to cigarette smoke. This causes an asthma attack. Long term exposure of the lungs to the irritants in tobacco smoke destroys the normal lung structure. The elastic walls of the small airways within the lungs are broken down. This reduces the amount of lung tissue available for the transfer of oxygen from the air to the blood. This condition is called emphysema. Some degree of emphysema is found in almost all people who are long-term smokers; however the severity will...

...Asthma (from the Greek άσθμα, ásthma, "panting") is a common chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm. Symptoms include wheezing, coughing, chest tightness, and shortness of breath. Treatment of acute symptoms is usually with an inhaled short-acting beta-2 agonist (such as salbutamol). Symptoms can be prevented by avoiding triggers, such as allergens[4] and irritants, and by inhaling corticosteroids Leukotriene antagonists are less effective than corticosteroids and thus less preferred. The prevalence of asthma has increased significantly since the 1970s. As of 2009, 300 million people were affected worldwide. In 2009 asthma caused 250,000 deaths globally. Despite this, with proper control of asthma with step down therapy, prognosis is generally good. Reaction: Suggestion: Chronic obstructive pulmonary disease (COPD), also known as chronic obstructive lung disease (COLD), chronic obstructive airway disease (COAD), chronic airflow limitation (CAL) and chronic obstructive respiratory disease (CORD), refers to chronic bronchitis and emphysema, a pair of commonly co-existing diseases of the lungs in which the airways become narrowed. This leads to a limitation of the flow of air to and from the lungs causing shortness of breath. In clinical practice, COPD is defined by its characteristically low airflow on lung function tests. In contrast to asthma, this limitation is...

...Pharmacogenomics 1.Introduction: Genomics: The study of genes and their function. Genomics aims to understand the structure of the genome, including the mapping genes and sequencing the DNA. Genomics examines the molecular mechanisms and the interplay of genetic and environmental factors in disease. It is used to determine the entire DNA sequence of an organisms and a fine scale genetic mapping. The field also includes study of intra genomic phenomena such as Hetrosis, Epistasis, Pleiotropy and other interactions between loci and alleles within the genome. 2.History: The term genome was introduced by H. Winkler in 1920 to denote the complete set of chromosomal and extra chromosomal genes present in an organism, including a virus. This term is used in the same sense even today. The term genomics was coined by T.H. Roderick sometime in 1987 mean mapping and sequencing to analyze the structure and organization of genomes. But today genomics includes sequencing of genomes, determination of the complete set of proteins encoded by an organism, and the functioning of genes and metabolic pathways in an organism. Thus genomics not only deals with the determination of the genetic information present in an organism, but also with the understanding the mechanism by which this information is used by the organism. A major branch of genomics is still concerned with sequencing the...

...There is no real risk-free level of exposure to secondhand smoke. The effect of secondhand smoke on individuals is hard to measure, however several studies have recognized an increase in respiratory conditions and lung cancer. According to Christian Heiss article in the Journal of American College of Cardiology, secondhand smoke increases a person’s risk of developing cardiovascular disease which is also a major public health concern. (Heiss) Even a very brief exposure to secondhand smoke can begin to have effects on the cardiovascular system and interfere with the normal functioning of the heart. When secondhand smoke is breathed in the platelets in the blood get sticky and may form clots which could lead to a heart attack. (U.S.) The risks...

...die younger than normal population. Smokers die 15 year younger than non smokers. In 21st century, 1.3 billion people will die of smoking. Smoking cigarette, pipe, cigar, Huqua, Shisha and other use of tobacco like chewing tobacco and tobacco sniffing all are dangerous and addictive. Nicotine present in tobacco smoke causes addiction by increasing the brain levels of chemicals like Dopamine and Endrophine. These chemicals give a sense of happiness hence there is craving for tobacco products. If a person tries to quit, withdrawal effects include irritability, anxiety, depression and lack of concentration. Tobacco and tobacco smoke have about 4,000 chemicals , 200 of these are poisonous and 60 of these chemicals are known to cause cancer (carcinogens). some of these chemicals are, benzene (a petroleum product), ammonia ( used in dry cleaning and toilet cleaning), formaldehyde (a chemical used to preserve dead bodies and ) and Tar.

...Why people smoke? Smokers think that they can quit and all the damages that have been done will go away and that they are risk free from diseases. That is not true. It is because people think it is cool. It is not so cool when you develop lung cancer and you will have to start going to hospital constantly to get check-ups and take a lot of medication. It will not be so cool when your unborn child has a big risk in having a defeat. It will not so be cool when you have a whole bunch of wrinkles on your face when you are young and the only way to get rid of them is by expensive surgery. Why you should quit smoking? First, smoking cause cancers. Smoking increase risk of many kind of cancers, especially lung cancer. Most of patients with lung cancer are smoker. Other cancers like cancer of colon, stomach, esophagus, nasopharynx, oral, tongue, breast, ovary, uterus etc are associated with smoking. Second, smoking can cause respiratory disease and more than 90% of patients with chronic obstructive airway disease (COAD). Patient with severe COAD are very disabling, can be breathless even at rest, and may need long term oxygen. Patient with COAD may eventually die from a COAD exacerbation or chest infection. It can trigger asthma, and make asthma difficult to control. Also, it can cause cardiovascular disease. Smoking causes atherosclerosis (hardening and narrowing of blood vessels), so increase risk of stroke, coronary heart disease and peripheral vascular disease. So patient may loss...

...Smog and carbon monoxide are two of the worst types of air pollution right now. Every type of car releases these pollutants.. So what does this pollutant cause? Pollution can actually make pre-existing illnesses worse. A main ingredient in smog, ground level-ozone, is dangerous to inhale because it can cause lung damage and upper respiratory problems. This ingredient is made from hydrocarbons and nitrogen oxide function with light from the sun and warm weather that creates this ground level-ozone. A car releases emission even if it is standing still (Motor Vehicle Pollution) The problem is more prominent in children and older people. Children are exposed to this danger every day and even worse when they go to school. Since their bodies immune system is not fully developed their exposure to this air pollution is more severe. For many children, getting on a school bus is the highest exposure to air pollution in there. While they are sitting there on the bus in highway they are inhaling large amounts of fuel combustion from all the other cars around them. Since children spend more time outdoors than adults they are exposed more to these toxins which can cause permanent lung damage, reproductive and genetic damage. (J. Wargo, L. Wargo, Aldermann...

...Ban Smoking in America Americans waste billions of dollars each year on tobacco products. Other drugs that are harmful, such as crack or marijuana, are illegal in the United States. If certain harmful substances are illegal, then cigarettes should not be permitted either. Smoking cigarettes are a proven killer of millions worldwide annually, but is perfectly legal. Cigarettes have a large affect on society in the area of environmental problems it carries with it. Smoking obviously pollutes the air and it definitely causes a lot of litter. People who smoke usually throw their butts anywhere such as out a car window, in someone’s yard, or even in a stream. Litter from cigarette butts is such a big problem because they take 18 months to 10 years to biodegrade. According to the New Jersey-based American Littoral Society, experts say: Cigarette butts rank at the very top of litter problems -- not just for their ubiquity, but for their toxicity and non-biodegradable nature…An estimated 1.7 billion pounds of cigarette butts accumulate in lakes, oceans, on beaches and the rest of the planet annually. (Carlozo) Not only are the cigarette butts ugly to look at, they also adversely affect wildlife. Cigarette filters are made to trap the carcinogenic agents in the tobacco and when they are thrown on the ground, those substances make their way into aquatic ecosystems which could be a threat to the quality of water. Also, there have been cigarette butts found in the stomachs of fish and...

...Respiratory disease is prevalent in New Zealand. Unfortunately, New Zealand has an extremely high incidence of respiratory-related diseases, such as asthma, lung cancer, pneumonia, bronchitis, and rheumatic fever. There are three main aspect of housing: damp houses, overcrowding, and indoor secondhand smoking. First, a warm, comfortable and ventilated housing is beneficial for humans’ health and wellbeing while, non-ventilated housing can cause a variety of health issues. According to Public Health Agency (2013), asthma may aggravate in cold, damp houses. Regional Public Health (2012) states that damp rooms cause dust mites to increase, which exacerbate asthma. Additionally, dampness or moisture encourages mould growth. Consequently, mould can irritate the airways of the lungs (Regional Public Health, 2012). This issue of cold and damp houses may be due to a leakage, inadequate ventilation and ageing of the house. According to Douwes (2009), the increased chemical emissions from building materials and floor covers may be due to the excess moisture. Moreover, inadequate ventilation is one of the causes of dampness; other potential harmful indoor pollutants may increase due to poor ventilation (Douwes, 2009). Likewise, insulation in the damp house may be difficult. According to Auckland Regional Public Health Service (2004), the microorganism was likely to increase in a favourable environment due to the increase of condensation indoors from cold air. According to Regional...
