Silicos disease form part of the lung disorder known as pneumoconioses and is characterized by nodules and fibrous scar tissue within the lungs. It is often caused by inhaling silica particles from the quartz in rocks, sand and similar other substances. These particles gets entrapped in the alveoli and macrophages that are present in the alveoli consumes the silica particles and died with the resulting inflammation attracting more macrophages, resulting into the formation of nodules and fibrous…

of the body it is located. An air embolism can also be cause if there has been damage to the lungs. If you are in an explosion the blast may force air into damaged arteries. Although air embolisms are extremely rare they do happen.…

obstructive pulmonary disease is any group debilitating, progressive, and potentially fatal lung diseases that have increased resistance to air movement, prolongation of the expiratory phase of respiration, and loss of the normal elasticity of the lung (Ignatavicius & Workman, 2012). Chronic obstructive pulmonary disease includes emphysema and chronic bronchitis. Emphysema is when the air sacs of the lungs are damaged and enlarged. Chronic bronchitis is inflammation of the mucous membrane in…

Can you imagine having your lungs fill up with a sticky substance so its hard to breathe? This is what happens to patients with Cystic Fibrosis or CF. Along with the lungs CF affects the pancreas, digestive system, and other organs of the body. In normal lungs the mucus is thin and helps coat and protect the airways making it a lot easier to breathe. In Cystic Fibrosis the mucus that acts like a lubricant in and on our organs turns very thick and sticky. This makes the air ducts and the tubes in…

It test how well you inhale and exhale, and it also test how much air your lungs take in with each breath. To perform this test, an instrument called a spirometer is used which measures the volume of air moving in and out of the lungs during pulmonary ventilation. When given this test a person can be standing up or sitting down but whichever one that person must remain in that position throughout the whole test. The person cannot change positions because that will mess of the results from the…

It also occurs when not enough oxygen can get from your lungs to your blood, mean it cannot be transported. Oxygen is not only needed for energy but also for other organs like the heart and brain so they can work to their best ability. However, this is not an actual disease and something which can occur when…

refer to a single disease but is an umbrella term for chronic lung diseases that irreversibly limits the flow of air in the lungs. CT imaging is able to perform in visualizing the effects of COPD. An advantage of CT over Lung Function Test (LFT) is that CT can differentiate between the different types of COPD, making it possible to classify the different subgroups of diseases. The below figure shows the difference in CT between lungs of a relatively healthy subject and that of a subject with…

damage the airway and the lining of the lung, which lead to a decrease in lung expansion, which then leads to trouble moving air in and out of the lung causing difficulty with breathing, Irregular breathing, Coughing, discoloration of the skin or nail due to the lack of oxygenated blood. According to case study, Mary had signs of COPD exacerbation which are hash productive cough and SOB, Mary symptoms are caused by the building up of fluid, mucus, and pus in her lung causing tightness of her…

Chronic Obstructive Pulmonary Disease is a progressive disease that makes breathing difficult. When having this disease, lung damage is produced. The disease worsens over time, although it is not treated, it can be slowed down. This is mainly caused by smoking, chemical fume, dust, and air pollution. Although there are many causes to this disease, smoking is the most common. It happens to over 12 million Americans and the risk factors can be environmental or genetics. COPD is largely preventable…

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…
