Describe the following structures that are part of the respiratory tubes and state their locations. a. pseudostratified epithelium – b. cuboidal epithelium – c. simple squamous epithelium – d. goblet cells – e. cartilage – f. smooth muscle – g. elastic fibers – h. cilia – 2. Patients experiencing asthma attacks are often advised to breathe through pursed (puckered) lips. How might this help reduce the symptoms of asthma? It helps because it causes general relaxation and improves ventilation. It also releases air trapped in the lungs. Lastly it keeps the airways open longer and prolongs exhalation to slow the breathing rate.…show more content…
If a tracheostomy bypasses the upper respiratory passages, how might the air entering the trachea differ from air normally passing through this tube? What problems might this cause for the patient? There is less mucus membrane exposure since the nose is being bypassed the air wont be filtered as well. There is no significant difference. 5. Certain respiratory disorders, such as emphysema, reduce the capacity of the lungs to recoil elastically. Which respiratory volumes will this condition affect? Explain the impact on gas exchange. Emphysema affects the maximal volume of air that can be exhaled. It also increases their RV (residual volume) and FRC ( Functional Residual Capacity) 6. If a person is receiving supplemental oxygen to restore blood oxygen levels, why might it be better to administer a combination of oxygen and carbon dioxide rather than pure oxygen? If you provide a combo of both, your body has to work harder to maintain the oxygen level because you are putting in both O2 and CO2. Your body will get rid of CO2. 7. Why is it impossible, under normal circumstances, for a person to hold the breath long enough to pass out? Because involuntarily control will take over and they will continue
