Cari’s Story
A. How could an infection in Cari’s nasal passages and pharynx spread into her sinuses? The infection could have easily traveled into her sinuses due to the fact of how close the passages and sinuses are to each other.
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 is deep inhalation followed by complete closure of the glottis and strong exhalation suddenly opening the glottis, and blasting air through the upper respiratory passages. Cari’s respiratory system is forcing out mucous in order to maintain enough space within her lungs for oxygen.
C. Which structures found in the terminal bronchioles and alveoli normally would protect cari’s lungs from infectious pathogens and particulate matter? Normally goblet cells secrete mucous to trap particles while cilia works by moving mucous towards the pharynx for removal. Cigarette smoke damages and destroys cilia, and causes goblet cells to produce increased amounts of mucous. The damaged cilia combined with increased mucous obstructs airflow in and out of the lungs.
D. How would the resistance of Cari’s airways be affected by excess mucus and fluid in her lungs? Excess mucous would build up within Cari’s lungs and her airflow will be hindered.
E. How would Cari’s lung compliance be altered as her alveoli fill with fluid due to pneumonia? Cari will have harder time breathing because her alveoli will not be able to efficiently exchange oxygen and CO2 in the blood.
F. How would fluid in Cari’s lungs affect her total lung capacity? Her total lung capacity will decrease due to the excess fluid taking up space in her lungs.
G. How does the elevation of Cari;s respiratory rate alter her minute ventilation? If the rate of her respiration increases then her minute ventilation increases and she may start to hyperventilate increasing CO2 in her blood stream leading to respiratory alkalosis.
