Asthma FACT SHEET

Asthma FACT SHEET Order Description Hello I 've got an example fail below could you plz use it as structure for this assignment. Asthma: The Respiratory System Asthma is a disorder of the respiratory system that blocks the airway makin" rel="nofollow">ing it difficult to breath. It is described as a reversible in" rel="nofollow">inflammation of the respiratory system. It is characterized by obstruction of airflow, hypersensitivity, and in" rel="nofollow">inflammation. Asthma is prevalent more in" rel="nofollow">in children than in" rel="nofollow">in adults. The disease is estimated to be affectin" rel="nofollow">ing more than 24 million people in" rel="nofollow">in the United States. Symptoms of Asthma Asthma is characterized by several symptoms most of which affect the components of the respiratory system. One of the key but not defin" rel="nofollow">initive symptoms is persistence coughin" rel="nofollow">ing that tend to occur durin" rel="nofollow">ing the night. The coughin" rel="nofollow">ing episodes sometimes can be triggered by laughin" rel="nofollow">ing or exercise. Other symptoms in" rel="nofollow">include shortness of breath, wheezin" rel="nofollow">ing, and chest tightness. Causes and Risk Factors for Asthma Asthma is triggered by allergens that can in" rel="nofollow">include pollen, in" rel="nofollow">infection, cold, and dust among others. The main" rel="nofollow">in risk factors for asthma in" rel="nofollow">include genetic composition, where one or more close family members have the condition. The other risk factor in" rel="nofollow">includes the presence of allergic conditions, for in" rel="nofollow">instance, atopic dermatitis or rhin" rel="nofollow">initis. Obesity and either active or passive smokin" rel="nofollow">ing can in" rel="nofollow">increase the odds of acquirin" rel="nofollow">ing asthma. Anatomy and Physiology of the Respiratory System The respiratory system is one of the most critical systems in" rel="nofollow">in the human body. It is located within" rel="nofollow">in the thorax, and its main" rel="nofollow">in function is facilitatin" rel="nofollow">ing gaseous exchange. Air that contain" rel="nofollow">ins oxygen is takin" rel="nofollow">ing in" rel="nofollow">into the lungs while carbon dioxide is breathed out of the body. The respiratory system is composed of the lungs, diaphragm, upper and lower airways as well as other muscles of respiration. Upper airways are made of the larynx, pharynx, and nasal cavity. On the other hand, the lower airways consist of the trachea, bronchi, and bronchioles. The air travels to the lungs from the upper airway to the lower airway and eventually to the alveoli in" rel="nofollow">in the lung parenchyma. The airways are always patent in" rel="nofollow">in normal conditions and allow free air movement and exchange in" rel="nofollow">in the alveolus. The alveoli have a large surface area and are rich in" rel="nofollow">in blood supply. The surface area and blood supply in" rel="nofollow">increase the efficiency of gaseous exchange in" rel="nofollow">in the lungs and in" rel="nofollow">increase the supply of the blood with adequate oxygen for metabolic requirements. Besides, the surface of the alveoli is made up of a thin" rel="nofollow">in, moist layer that dissolve the air facilitatin" rel="nofollow">ing diffusion in" rel="nofollow">into the blood capillaries. The airways are made up of smooth muscles that play the role of adjustin" rel="nofollow">ing the lumen of the pathway dependin" rel="nofollow">ing on the oxygen demands. The in" rel="nofollow">inner walls of the airways are also covered with mucous that moistens and warms the in" rel="nofollow">inhaled air. Asthma Pathophysiology Asthma occurs when the hypersensitivity airways are triggered by allergens such as pollen, cold, hay, smoke, or dust among others. The presence of allergens stimulates the body to produce Immunoglobulin" rel="nofollow">in E that activates mast cells. Mast cells produce histamin" rel="nofollow">ine and other cytokin" rel="nofollow">ines that facilitate in" rel="nofollow">inflammation of the airways, hyper secretion of mucous, and mucosal edema. These events lead to narrowin" rel="nofollow">ing of the airways hence obstructin" rel="nofollow">ing the normal smooth airflow to and from the lungs. Asthma Diagnosis and Treatment The best approach used in" rel="nofollow">in diagnosin" rel="nofollow">ing asthma is by takin" rel="nofollow">ing the comprehensive medical history of the patient, lung function test as well as clin" rel="nofollow">inical or physical examin" rel="nofollow">ination. Asthma is managed by use of appropriate medication dependin" rel="nofollow">ing on the severity and age of the patient. Asthma as six treatment steps where the first step is mild sickness and the last step is a severe disease. The medications used to treat asthma in" rel="nofollow">include short-actin" rel="nofollow">ing beta two agonists such as salbutamol and in" rel="nofollow">inhaled corticosteroids for in" rel="nofollow">instance budesonide. Other drugs in" rel="nofollow">include long-actin" rel="nofollow">ing beta two agonists for example eformoterol, leukotriene receptor blockers such as montelukast and cromones. Cromones are mast cell stabilizers and in" rel="nofollow">include nedocromil sodium and sodium cromoglycate. Defin" rel="nofollow">initions Inflammation: It is the state whereby a part of the body becomes swollen, reddened, warm and sometimes pain" rel="nofollow">inful. Airways: The pathway through which air gets in" rel="nofollow">in or out of the lungs. Hypersensitivity: Refers to undesirable reactions produced by the body’s immune system due to in" rel="nofollow">intolerance of some substances. Allergen: A substance that triggers immune response resultin" rel="nofollow">ing in" rel="nofollow">in hypersensitivity or allergic reactions. Immunoglobulin" rel="nofollow">in E: It is a group of antibodies produced by the body’s immune system followin" rel="nofollow">ing exposure to an allergen. References Bislimi, A. H., & Tolka, L. C.
