Lung

What is the difference between the upper and lower respiratory tracts? The upper airways or upper respiratory tract is the parts of the respiratory system lying above the glottis (Vocal cords) • Nose – External breathing organ. • Nasal passages, Inside the nose, the sticky mucous membrane lining the nasal cavity traps dust particles, and tiny hairs called cilia help move them to the nose to be sneezed or blown out • Paranasal Sinuses, - These air-filled spaces alongside the nose help make the…

molecules. As the body inhales, oxygen from our environment is taken into the body. As oxygen approaches the respiratory membranes in the lungs, the concentration is higher on the outside of the membranes than on the inside and causes the oxygen to move inward. The carbon dioxide concentration moves opposite of the oxygen thereby pushing it out of the lungs when the body exhales. The process of taking in oxygen from the air, it being transferred to the bloodstream and the carbon dioxide…

reversible airflow obstruction and an abnormal inflammatory response in the lungs (MacNee, 2006). In many peer research articles, the articles have addressed the diagnosis and assessments of people with COPD, as well as the pharmacological and the non-pharmacological management of stable disease and exacerbations. Chronic obstructive pulmonary disease is characterized by chronic inflammation of the airways, tissue of the lungs and pulmonary blood vessels. These obstruction’s are caused by…

They are also used for short and long term relief of certain symptoms that come with COPD. ” Studies show that inhaled beta2-agonists are effective in treating symptoms of COPD and improving lung function as measured by tests (spirometry). They also reduce the number of COPD exacerbations (Celli, 2008). The preferred use of β2 agonists are through inhalation because they cause the smooth muscle relaxation. “Long-acting bronchodilators are preferred…

instead of just letting people get the part free. Zachary became a mouth breather because his lungs got asthma. However, these lungs weren’t his, it was from an unwind- Harlan Dunfee, son of the leader of the Graveyard. The novel stated, "When I was little, I was diagnosed with pulmonary fibrosis. Both my lungs were shutting down. I was gonna die. So they took out both my dying lungs and gave me a single lung from an Unwind."..."Like I said, the lung's got asthma. It was the best we could…

common dusts to cause pneumoconiosis. Some Suppurative and Necrotic conditions of the Lower Respiratory Tract include Pyothorax, Pneumothorax, and Abscess of the Mediastinum. Pyothorax or also known as Empyema, is where pus gathers in between the lungs and inner surface of the chest wall. Pyothorax (J86.0, J86.1), usually develops after pneumonia. The pus can not be coughed out but drained out by a needle or even surgery. The most common bacteria that causes Pyothorax is Streptococcus…

increased perivascular inflammation as well as chronic alveolar inflammation, alveolar wall thickening and swelling, granulomatous lesions, and alveolar macrophage accumulation (Cho et al, 2003). A parallel study found the same type of lung damage accompanied by a decrease in lung function, indicated by the tidal volume, minute volume, and peak inspiratory flow, which persisted throughout a 12-week recovery period (Song et al,…

In late 2013, my grandmother was diagnosed with pulmonary fibroses, a terminal disease that slowly hardens and deteriorates the lungs. She was given about a year to live and the entire family was crushed. This was a very trying time for my family and me, but luckily it didn’t end in tragedy. This situation helped me appreciate the value of the ones you love and made me grateful to be alive. On my 14th birthday, in late April, I was worried it was the last one I’d have my grandma to celebrate…

intrapulmonary pressure, atmospheric pressure and airflow within the lungs. “Intrapulmonary pressure is the pressure within the lungs, atmospheric pressure is the pressure used in all directions at any given point by the weight of the atmosphere and air flow is simply the motion of air. Intrapulmonary pressure and atmospheric pressure are usually measured in units of millimeters of mercury. “Inspiration is the act of drawing air into the lungs and expiration is the exhalation of breath…

secondary. Each type of spontaneous pneumothorax has a particular pathology and incidence that, in each case, leads to a particular way of treatment and monitoring. In general, a pneumothorax occurs when there is air present in the pleural cavity of the lung, however the underlying cause of this pathology varies among the different classifications. Surgical or non-surgical approaches are taken, depending on the severity or type of the pneumothorax. The purpose of this paper will be to discuss…
