Asthma is a disorder of the respiratory system in which the passages that enable air to pass into and out of the lungs periodically narrow, causing coughing, wheezing, and shortness of breath. This narrowing is typically temporary and reversible, but in severe attacks, asthma may result in death. Asthma most commonly refers to bronchial asthma, an inflammation of the airways, but the term is also used to refer to cardiac asthma, which develops when fluid builds up in the lungs as a complication of heart failure. This article focuses on bronchial asthma.
More than 17 million Americans suffer from asthma, with nearly 5 million cases occurring in children under age 18. In the United States, asthma causes nearly 5,500 deaths each year. Asthma

Asthma Attacks
Asthma attacks occur when the bronchi and bronchioles become inflamed, reducing the space through which air can travel through the lungs. This causes the asthmatic to work harder to move air in and out of the lungs. Asthma attacks usually begin with mild chest pressure and a dry cough. As an attack intensifies, wheezing develops and increases in pitch; breathing becomes difficult; and coughing produces thick, stringy mucus. As the airway inflammation prevents some of the oxygen-rich air from reaching the alveoli, the cells of the body start to burn oxygen at a higher rate, actually increasing the body’s demand for oxygen. The frequency of asthma attacks varies considerably among asthma suffers. Some people have daily attacks, while others can go months or even years without having an attack.
Inflammation of the airway occurs when an irritant—such as pet hair or cigarette smoke—comes into contact with the airway walls. Upon detecting the irritant as a harmful invader, the body’s immune system sends special cells known as mast cells to the site of irritation, in this case the airway walls. The mast cells release histamine, a chemical that causes swelling and redness in a process called the inflammatory response. Histamine also causes bronchospasms, in which the muscles lining the airway walls contract repeatedly, causing the airways to narrow even more. In addition, cells that lubricate the airways with mucus—called
Throughout the years knowledge about asthma has grown, as well as treating it effectively. Over 300 million people are said to be victims of this disease with another 100 million being estimated by 2025 globally (Currie and Baker, 2012). In the United Kingdom, asthma is increasingly becoming one of the leading disease affecting individual of different age, ethnicity, race and gender. British Lung Foundation (2011) stated that it is more common at childhood stage and can also occur at a later age. According to Asthma UK (2014) asthma in men is less prevalence than it is in women and children troubled more with asthma than adults. Recent data in the UK shows that in children and occupational asthma in adult is on the rise with an estimate
Your airway has smooth muscles around the outside of the airway tubes also known as bronchial tubes. The tubes are open allowing air to flow freely; during an asthma attack those muscles begin to tighten that is called a bronchospasm restricting the airflow. During an asthma attack the lungs also become inflamed and the mucus in the tubes begins to become thicker and builds up, this makes it even more difficult for air to pass through the opening of the tubes. With the airway being restricted and the mucus build up causes a wheezing sound and shortness of breath and difficulty in inhaling and exhaling air (WebMD).
It is difficult to obtain an accurate count of people living with asthma because many of its symptoms can be attributed to allergies or other health problems such as sinusitis or pneumonia.
Asthma is a chronic inflammatory disease of the airway that impacts a person’s and their family’s quality of life. In people with asthma, their airway becomes constricted with swelling and excessive mucous. This constriction or narrowing of the airway makes it difficult for the person with asthma to breath (Massachusetts Department of Public Health, 2009). If asthma is left uncontrolled, it leads to further wheezing, coughing, shortness of breath, tiredness, and stress. (Massachusetts Department of Public Health, 2009).
Asthma is a disease that affects your lungs. It causes repeated episodes of wheezing, breathlessness, chest tightness, and nighttime or early morning coughing. Asthma can be controlled by taking medicine and avoiding the triggers that can cause an attack. You must also remove the triggers in your environment that can make your asthma worse.
Asthma is an inflammatory condition of the airways causing attacks of wheezing and breathlessness. It affects a person’s
1. Asthma as a word means, “To breathe hard.” Just as the definition of the word, people with asthma have a hard time breathing, tightness in the chest and wheezing can occur. It is also a chronic disease of the respiratory system, which the respiratory passages in the lungs become oversensitive and overactive. (i)
Asthma affects people of all ages, but it most often starts during childhood. Asthma is a chronic lung disease that inflames and narrows the airways, which are tubes that carry air into and out of your lungs allowing one to take in oxygen and breathe out carbon dioxide. The swelling also can worsen, making the airways even narrower and the ability to breathe more difficult. Sometimes asthma symptoms are mild and go away on their own or after minimal treatment with asthma medicine, but other times symptoms continue to get worse. When symptoms get more intense and more symptoms occur, you 're having what is commonly known as an asthma attack. During an asthma attack you are in complete panic and the swelling in your airways reaches a point where it is no possible to take air into the lungs. If action is not taken to reduce the swelling of the airways in order to restore breathing, someone could die of asphyxiation, or the lack of oxygen. The number of people being diagnosed with asthma is on the rise, especially in the rates of children developing symptoms of asthma at a young age.
Asthma is a long-term lung disease. Those with asthma have sensitive airways in their lungs which triggers a flare up. When this flare up happens the muscle around the airways squeeze tight and the airways swell, become narrows and produce more mucus. (Anon., 2016) All these things make it harder for a person to breathe. Asthma effects the human body’s respiratory system. Asthma causes a spasm and constriction of the bronchial passages and the swelling and the inflammation of the mucous lining. The body responds by defence cells from the immune system, which causes the airways to swell and the muscles surrounding the airways to contract. Which is what cuts off the airflow. While a person is in asthma attack, the asthmatic cannot breathe which
According to the National Heart, Lung, and Blood Institute, Asthma is a chronic lung disease that affects the airways, which is comprised of tubes that carry air in and out of the lungs. People who experience difficulties breathing have inflamed airways. The inflammation causes the tubes to swell and become sensitive, especially when inhaling strong substances. As a result, the airways tighten and the muscles around the tubes become swollen and narrower. In addition, cells in the airways might produce more mucus. This sticky and thick mucus makes it even more difficult for air to pass into the lungs.
In Joseph Conrad’s Heart of Darkness, Charlie Marlow shows the truth that man lives in a world of lies and deception. He does this by showing the depictions of western colonization in Africa through his journey and experiences he went through. The novel itself exposes the cruelty of the western civilization and the corrosive and ruinous power it brings not only onto Africans but also to the Europeans as well. This goes to show how people deceive for selfish desires and how everyone stands on different levels of deception through the lies of western civilizations, lies of the man’s world, and through the people’s hatred of the lies.
Asthma is a chronic disease of the airways that makes breathing difficult. With asthma, there is inflammation of the air passages that results in a temporary narrowing of the airways that carry oxygen to the lungs. When this inflammation occurs, the asthma symptoms start to show, such as, coughing, wheezing, shortness of breath, and chest tightness. Even though there are many treatments for asthma symptoms, it is still a very serious disease that affects more than 22 million Americans and brings nearly 2 million E.R. visits per year. Asthma can be lived with very well as long as proper treatment measures are taken (Wrongdiagnosis).
Breathing is a vital process for every human. Normal breathing is practically effortless for most people, but those with asthma face a great challenge. During an asthma attack, breathing is hampered, making it difficult or even impossible for air to flow through the lungs. Asthma is an increasingly common problem, and has become the most common chronic childhood disease. At least 17 million Americans suffer from it(1), and although it can be fatal, it is usually not that severe(4). There is no cure for asthma, but with proper care, it can usually be controlled.
The Epic of Gilgamesh does not quite have a happy end. Truthfully, Gilgamesh is not successful in his mission. It is shortsighted and deceived to expect that Gilgamesh, the saint, must be effective in his journey to hold the characteristics of courage. An unsuccessful journey not harsh any more than a courageous ending is essentially joyful. For recognitions of this, we need to look no more distant than the plenty of thoughtful legends of great writing – the stories of Homer, Virgil 's Aeneid, and even Beowulf of the Anglo-Saxon abstract convention. The Illiad end with the slaughter of Troy and the passing of Achilles. The Odyssey, in spite of the fact that it sees the saint restored home, in any case includes an entirely tough cost. The Aeneid, in like manner, shows in disaster. Like Achilles, Odysseus, Aeneas, and various other exemplary legends, Gilgamesh too shows those qualities vital to an ordinary scholarly saint, none of which needs to do, truth be told, with the unique idea of pleasure. In spite of the fact that achievement is quite unimportant to the bravery of a specific journey, maybe the first indicate considered in "Gilgamesh" is that the legend might really make progress. His level of progress depends to a limited extent on what he needs to accomplish and what he accomplish. Given the included creative component of the epic that they are developments of one or more creators the accomplishment
With the growing fear of nuclear war with North Korea, the threat of terrorism in the Middle East, or the threat of domestic terrorism in the United States, people tend to forget the threat that climate change has on the world. Many people believe in climate change, but some people do not know the significance it may have on the world. The dangers are unclear, but there is a consensus in the science world that the earth and its inhabitants need to take climate change a lot more seriously. While there are necessary measures being taken like the Paris Agreement, it is imperative that people also take into account their carbon footprint and try to reduce the amount of carbon dioxide released into the atmosphere to ensure a better future for the upcoming generations and generations that develop after that. We do not want to live on a planet that may become too hot to live on, in some places. By examining the effects of climate change and other factors, people should be open to change and be determined, not in denial of the facts not only proved by scientists, but observed as well.
