Asthma is an obstructive airway disease where airway resistance is increased and inflammation is present. This inflammation and obstruction (narrowing of the airways) result in an increased resistance of expiratory airflow, and expiration is not passive, but need aid from expiratory muscles.…
I already knew that asthma is a chronic disease which affects the lungs and that…
With asthma, the muscles in the airways tighten and the lining becomes swollen and inflamed, producing sticky mucous. These changes cause the airways to become narrow, making it difficult to breathe.…
Asthma Attack – An asthma attack is a sudden worsening of asthma symptoms caused by the tightening of muscles around the airways. During an asthma attack, the lining of the airways also become swollen or inflamed and thicker mucus, more than normal, is produced. All of these factors, cause symptoms of an asthma attack such as difficulty breathing, wheezing, coughing, shortness of breath and difficulty performing normal daily activities.…

Asthma is a chronic condition of the respiratory system that causes hypersensitivity and reversible inflammation of the airways resulting in breathing difficulties (Levy et al., 2006).…
Asthma is a chronic disease of the lungs and one of the most common long term diseases in children ("Asthma ", n.d). The actual cause of asthma is unknown and there is currently no cure, but certain things in the environment trigger the inflammation of the airways, ultimately leading to asthma attacks. However, it is manageable and can be prevented by avoiding your triggers. Triggers vary for every person, but the most common are tobacco smoke, dust mites, pets, and pollution ("Asthma ", n.d). The symptoms include tightness in the chest, coughing, and wheezing ("Asthma ", n.d). Asthma attacks can be deadly if they are not taken care of right away. During an attack the airways in your lungs shrink and do not allow enough air to pass through.…
The 3 main features of asthma include airway obstruction, inflammation, and airway irritability. Normal breathing for the human body includes air moving freely to and from the lungs but, with asthma the bands of muscle around the airways tighten causing the airway to not be able to go through freely. In other words, the lungs do not get enough air and this causes the human to feel a shortness of breath or to have trouble breathing—this is known as airway obstruction.…
Asthma is just a general term for what is going on, there are three types of asthma. Each asthma name base off of what triggers the asthma attack. The three types of asthma are allergic asthma, mixed asthma and idiopathic asthma. Allergic asthma occur due to an irritants such as allergens trigger the asthma attack. This occurs due to the fact that the allergens aren’t recognized by our body’s immune system. Since it is unrecognizable it causes the white blood cells in our body to recognize it as a threat. This then promotes our helper T cells to activate the production of B cells which then causes antibiotics to be made. The production of the B cells signals the thymus to make more lymphocytes. The allergens have often just settled within our airway. The production of more white blood cells (specifically immunoglobulin E cells) causes the area to become inflamed. The inflammation of the airway causes the bronchioles to contract (get tighter) which leads to the patient to have trouble with breathing. Allergens such as pet dander, pollens, spores and dust mites are usually responsible for setting off an allergic asthma attack. The second type of asthma is idiopathic asthma. The reason why this is called idiopathic asthma is due to the fact that the exact reason why it is triggered during specific events is unknown. Idiopathic asthma is usually triggered by respiratory infection, exercises and emotional upsets. These thing can lead to an asthma attack due to the fact that they can cause the bronchioles to…

Asthma is a common long term condition that can cause cough, wheezing and breathlessness. These are severity of the symptoms which can vary from person to person, and asthma can be controlled well in most people most of the time. Asthma is caused by inflammation of the airways, these are small tubes called bronchi which would carry oxygen in and out of the lung, as the individual bronchi would inflame and become more sensitive than normal, when the individual comes into contact with something that irritates his lungs (trigger off) his airways become narrow and the muscles around the lungs tighten which makes…

1.) The organ system asthma affect is the respiratory system (the lungs). Asthma is diagnosed based on medical and family histories, a physical exam, and test result. During an asthma attack the person have an acute episodes when the airways in their lungs become narrow and becomes more difficult to breath. The lungs and airways overreact to certain triggers, in which the lining of the airways become swollen and inflamed, tightness of the chest, and increased of mucus in the lungs. It is harder to breath and may hurt too. Coughing and wheezing are common in asthma. Wheezing occurs because the rush of air moves through the narrowed airways. There are two types of medication to treat asthma.…
When it comes to human health related to air pollution there are increasing mortality rates within large cities across the United States. One notice cause within the increase of air pollution is asthma. Asthma is an ongoing problem within the United States directly affecting children. Many epidemiological studies have been conducted in an attempt to pinpoint the cause of asthma. Asthma is considered a long term effect of air pollution as it can deal with either indoor or outside pollution. Another health effect of air pollution is coronary heart disease. Those who have a preexisting heart condition such as coronary heart disease are more susceptible to different forms of air pollution. Different forms of air pollution could cause those with…
