Asthma is a chronic disease that effects the airways to the lungs causing inflammation, irritation, and difficulty breathing. Most of you may not think of asthma as a killer disease, yet more than 5,000 Americans die of asthma each year. According to the Mayo Clinic web page, asthma also accounts for more than 400,000 hospital discharges annually. As the number of people with asthma increases, the more likely you are to meet a person who has the disease. I have had asthma my whole life but as I…

to the respiratory system of a smoker. One extremely widespread change is Chronic Obstructive Pulmonary Disease (COPD). The World Health Organisation (2010) define COPD as, “…a lung disease characterized by chronic obstruction of lung airflow that interferes with normal breathing and is not fully reversible.” COPD as a lung disease encompasses pathological changes such as Chronic Bronchitis and Emphysema. Chronic Bronchitis is long term inflammation of the main bronchi, which instigates…

Experiment 14.1 The Histology of the Lung Introduction: This experiment will give you a change to see an alveolus, a capillary, and the respiratory membrane. Procedure: I studied a slide of a lung tissue and observed the various structures, mainly the alveoli, capillaries, and the respiratory membrane. I then drew pictures of the structures in different microscope powers. Summary: Very briefly, we will discuss how air travels to the lungs. First, air travels down your larynx, and then into…

symptoms, standard inhaled medication and explore a newer long-acting muscarinic antagonist bronchodilator as Global initiative for Chronic Obstructive Lung Disease (GOLD) guidelines recommend. COPD is chronic inflammation of the airways that cause changes and destruction leading to the obstruction of airflow. The deterioration of normal lung tissues results in a decrease in expiratory flow and…

is usually progressive and is associated with an inflammatory response of the lungs (Haggerty, 2013). The pathological changes that indicate COPD include an increase in mucus producing cells, chronic inflammation in different parts of the lung, and structural changes that result from a persistent cycle of destruction and repair. Many parts of the lungs are affected, including the proximal and peripheral airways, lung parenchyma, and pulmonary vasculature (Haggerty, 2013).The inflammatory…

Pleural mesothelioma is a uncommon melanoma often medically clinically diagnosed in individuals who have used great levels of mesothelioma. The metastasizing melanoma effects the pleura, a thin cells part of lubricating cells that selections the breathing and chest area place surfaces. It sometimes needs a several years or more for changes to appear that are an indicator of pleural illness, and for a long time for symptoms to show. These modifications normally consist of a thickening or…

Chronic inflammation in the airways limits the amount of airflow to the lungs. It is progressive and relates to abnormal inflammatory response in the lungs that affects gas exchange. “This is caused by loss of elastic recoil and airflow obstruction caused by mucosal hypersecretion, mucosal edema, and bronchospasm”. One of the two Chronic Obstructive Pulmonary Disease (COPD) is chronic bronchitis. It is caused when the bronchi and bronchioles become inflamed by exposure to smoke or environmental…

on having a double lung transplant at some point this year after she relocates to Duke. Doctors have worked very hard and long to help Nicole through this process. Nicole travels all the way to New York every three-four…

The lung wall is delicate which makes it susceptible to surface tension injury. The wall is made of epithelium, which is tissue that lines the cavities and surfaces of organs in the body. When complications with infections occur regions of the lung can fill with fluid, also babies born premature can have underdeveloped lungs causing increased surface tension. These cause the lungs to remain closed, a disease called respiratory distress syndrome. The deformation of biological cells when…
