A.) How could 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 sinuses being a drainage area for the nasal passages. B.) What is the couch reflex? 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 abundant, it triggers the cough reflex.
C.) Which structures found in the bronchioles and alveoli normally would protect Cari’s
lungs from infectious pathogens and particulate 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 airway be affected by excess mucus and fluid in her lungs?
Airflow decreases when there is greater resistance in the airways and increases when there is decreased resistance. The excess mucus and fluid in the lungs would increase the resistance of Cari’s airways because of the small diameter the buildup would cause.
E.) How would Cari’s lung compliance (the effort required to expand the lungs) be altered as her alveoli fill with fluid due to pneumonia?
Cari would have low compliance meaning that the lungs resist expansion.
Decreased lung compliance is a common feature in pulmonary conditions cause
lung tissue to become filled with fluid. F.) How would fluid in Cari’s lungs affect her total lung capacity?
The fluid in Cari’s lungs would lower her total lung capacity by not allowing the
space that is taken up by the fluid to be filled with air. G.) How does the elevation of Cari’s respiratory rate alter her minute ventilation?
The elevation of Cari’s respiratory rate would result in a lower than...
