chose is Chronic Obstructive Pulmonary Disease. Individuals with chronic obstructive pulmonary disease may experience trouble with breathing, and coughing. Chronic obstructive pulmonary disease (COPD) is a term that is used to described a progressive lung disease. One of the biggest causes of COPD is cigarette smoking, and secondhand smoking. Pollutants that are found in the environment like fumes and chemicals can also contribute to COPD. According to the COPD Foundation, chronic obstructive…

The second criterion that defines a disease is that a disease usually worsens if left untreated. Although not all diseases can be cured, most of symptoms and effects caused by a disease can be lessened with medications, therapy, surgery, and other treatments. For instance, a person born with asthma, a condition where the airway is being infected and swollen by certain factors such as dust or pollen, can live a healthy and productive life if he or she receives suitable treatments. Although it…

isn’t a struggle. Asthma is a common long term inflammatory disease of the airways. From my reading of what asthma is on the Society of Asthma website I have discovered that it affects the airways in your lungs. The airways (alveoli) in your lungs have small tubes that carry air in and out of the lungs. The Asthma Society of Ireland says that when the airways become sensitive to the cold or dust, this irritant then causes the muscles around the wall of the airway to tighten up making it…

Disease Chronic obstructive pulmonary disease (COPD) is a progressive disease of the lungs that causes obstruction of the airways and results in a gradual decline in the function of the lung (Stark). COPD is typically a combination of emphysema and chronic bronchitis. COPD has been around for a very long time, however, in previous decades it was called something else. In 1679 physician Bonet called it, ‘voluminous lungs’. In 1814 Charles Badham was the first person to refer to ‘catarrh’, meaning…

leading to a compromised defense for the lungs. Since the lungs have a compromised defense, they are more prone to infection. COPD exacerbations are linked to lung infections. Emphysema is the second phenotype of COPD and affects the tissues differently than chronic bronchitis. In emphysema there is a permanent change in lung tissue. The gas exchange airways are enlarged and the alveoli are destroyed. The airways are not narrowed, rather the elastic recoil of the lungs leads to limited airflow.…

mast cells to create the IgE mast cell complex. T helper 2 cells itself through interleukin 9, will stimulate mast cell activity. Another thing T helper 2 cells will do is promote eosinophil production from bone marrow through interleukin 5 to the lungs. The inhaled allergen will bind to IgE mast cell complex which causes the mast cell to release histamine, prostaglandins and leukotrienes. All this histamine will stimulate smooth muscle in the airways to cause constriction also known as…

Abstract. Aim. To show case report on proximal infiltration of early caries lesion. A 22-year-old female was admitted in Department of paediatric and preventive dentistry, School of Dental Medicine, University of Zagreb with finding of early enamel lesion on proximal surface of molar. Radiograph was taken and caries lesion was detected on proximal surfaces of lower left first molar including enamel and outer part of dentin surface. The patient complaints of sensitivity to cold and sweet. ICON…

on my brother’s life since he was diagnosed at the age of 3. Asthma is a chronic inflammatory condition of the lungs that affects the airways of its victims. It causes narrowing of the airways which then interferes with air moving in and out of the lungs. Asthma affects the bronchial tubes of the lungs, but not the air sacs. When the airway reacts, all the muscles around the lungs tighten up and prevent even more oxygen from entering in. As the body responds to the stress,…

Bronchitis is an inflammation of the bronchial tubes, or bronchi, that bring air into the lungs. Inflammation is a chemical reaction in the body that produces redness, swelling, and pain. When the cells lining the bronchi are irritated, the tiny hairs (cilia) that normally trap and eliminate things from the outside stop working. Formation of material associated with irritation swelling also increases; causing the passages to become clogged. The same viruses that cause colds, often cause acute…

Powerlab 4 Questions When taking our subject’s different capacities, we found that her inspiratory capacity (IC) was 5.58 L, vital capacity (VC) was 5.85 L, functional residual capacity (FRC) was 1.74 L, and her total lung capacity (TLC) was 7.32 L. When comparing these numbers to the averages for a woman’s capacity we find that: her IC was more than double of that of an average woman (5.58 L compared to 2.4 L); her vital capacity was greater than average as well (5.85 compared to 3.1 L).…
