...Cari’s Story Unit 5 Case Study 1 Amanda Egan (19215107) A&PII Instructor Dr. Lok 7/21/2015 A.) How could an infection in Cari’s nasal passages and pharynx spread into her sinuses? Mucous membranes of the nose, parasinal sinuses, pharynx and middle ear are connected by ducts in the throat. B.) What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing. A Cough reflex is a long-drawn in and deep inhalation followed by a complete closure of the glottis, which results in a strong exhalation that suddenly pushes the glottis open and sends a blast of air through the upper respiratory passages. This process is clearing her lungs by forcing foreign bodies out of the larynx, trachea and epiglottis. C.) Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter? There are macrophages presents (wandering phagocytes) that remove dust particles and other debris from the alveolar spaces D.) How would the resistance of Cari’s airway be affected by excess mucus and fluid in her lungs? The lung capacity is decreased because the air space is already filled with mucus and fluids therefore she can’t take in enough oxygen. The extra mucus and fluids put extra pressure on the lungs. E.) How would Cari’s lung compliance (the effort required to expand the lungs) be altered as her alveoli...

...Cari’s Story Ap2630 ITT Technical Institute Warrensville Heights January 13, 2016 A. An infection in Cari’s nasal passages and pharynx can spread to her sinus because all three are connected by ducts in the throat so; infection easily travels via mucus from one to the other. B. Cough reflex is a long-drawn and deep inhalation followed by a complete closure of the glottis, which causes a strong exhalation that pushes the glottis open and sends a blast of air through the upper respiratory passages. This process is clearing her lungs by forcing foreign bodies out of the larynx, trachea, and epiglottis. C. Macrophages would normally clear the alveolar space in Cari’s lungs from foreign particles that could cause infections. D. Excess mucus and fluid in the lungs would raise the resistance of Cari’s airways because the buildup would cause the diameter to become smaller. The fluid would cover some of alveoli and prevent them from functioning properly and there would be more friction from the buildup. E. Cari’s alveoli being filled with fluid due to pneumonia lung would cause her lung compliance to increase from trying to force gases into and out of the alveoli. F. Fluid in Cari’s lungs would decrease her total lung capacity by preventing the space that is occupied by fluid to be filled with air. G. Elevation in Cari’s respiratory rate would alter her minute ventilation by raising it. H. The clinical finding of 90% oxygen saturation level and a...

...A. How would an infection in Cari’s nasal passages and pharynx spread into her sinuses? An infection would spread into Cari’s sinuses due to the sinuses being a drainage area for the nasal passage. B. What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing? A cough reflex clears up sputum from the nasal passages and pharynx. In the trachea there are cilia that move mucus up from the lungs. The mucus causes the cough reflex. C. Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter? Inside the terminal bronchioles and alveoli there are macrophages that would protect Cari’s lungs. D. How would the resistance of Cari’s airway be affected by excess mucus and fluid in her lungs? Due to the buildup of excess mucus and fluid in Cari’s lungs, she would have a difficult time with her breathing since the alveoli could not function properly since they would be submerged under fluid. E. How would Cari’s lungs compliance (the effort required to expand the lungs) be altered as her alveoli fill with fluid due to pneumonia? Her lung compliance will increase from trying to force the gases into and out of the alveoli. The fluid that is in her lungs is pneumonia. F. How would fluid in Cari’s lungs affect her total lung capacity? The fluid in her lungs affect her total lung capacity by decreasing the amount of air into...

...Unit 5 Case Study Halstead Unit 5 Case Study: Cari’s Story A. How can an infection in Cari’s nasal passages and pharynx spread into her sinuses? The infection in Cari’s nasal passages and pharynx was able to spread into her sinuses due to the fact of how close the passages and sinuses are to each other, and the sinuses being a drainage area for the nasal passages. B. What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing. The cough reflex involves deep inhalation followed by complete closure of the glottis and strong exhalation with sudden opening of the glottis, and forcing air through the upper respiratory passages. The cough reflex is used to clear sputum and irritants that are in the nasal passages and pharynx. Cari’s respiratory system is forcing out mucus in order to maintain enough space within her lungs for oxygen. There are cilia in her trachea that is moving mucus up from the lungs. When there is much mucus, it triggers the cough reflex. C. Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter? Goblet cells secrete mucus to trap particles while the cilia work by moving mucus towards the pharynx for removal. Macrophages are also found in the terminal bronchioles and alveoli; they engulf and destroy infectious pathogens and particulate matter. D. How would the resistance of Cari’s airways...

Describe the process that Cari’s respiratory system is using to clear her lungs by coughing. The cough reflex is used to clear sputum and irritants that are in the nasal passages and pharynx. There are cilia in her trachea that is moving mucus up from the lungs. When the mucus becomes or abundant it triggers the cough reflex C. Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particular matter? There are macrophages found in the terminal bronchioles and alveoli that normally would protect Cari’s lungs from infectious pathogens and particulate matter. D. How would the resistance of Cari’s airways be affected by excess mucus and fluid in her lung? The excess mucus and fluid in the lungs would raise the resistance of Cari’s airways because of the small diameter the buildup would cause. The fluid would have some of alveoli under water where they could not function properly and there would also be more friction from the buildup. E. How would Cari’s lung compliance (the effort required to explain the lungs) be altered as her alveoli fill with fluid due to pneumonia? Cari’s lung compliance...

How would the resistance of Cari’s airways be affected by excess mucus and fluid in her lung? Cari’s airway would be affected by excess mucus and fluid buildup because the build up would cause resistance in her lungs due to the small diameter of space that is available.
