Exam 11
| Question | Answer |
|---|---|
| Gas exchange occurs in which of the following areas | alveolar ducts, pulmonary capillaries, and respiratory bronchioles |
| In which vessel is hemostatsis NOT typically very effective? | Viens or arteries |
| Which of the following would you give to a patient to promote hemostatsis? | fibrin |
| Which of the following happens during inhalation? | the diaphragm shortens, the width of the pleural sac does not significantly increase, and the thoracic cavity increases in size |
| Surfactant is produced by ____ cells so that ____ can function properly | Type II-alveoli |
| When the diaphragm is relaxed, the pressure inside of the lungs is ____ and air flows ____of the lungs | increased-out |
| With decreased activity, the venous reserve will ____and the venous pH will ____. | increase -increase |
| Oral anticoagulants have the most direct impact on which stage of hemostasis? | clot formation |
| Hemoglobins affinity for oxygen ___ when ____ is/are present | decreases-carbon dioxide, hydrogen ions, and/or a high temperature increases-a high oxygen level |
| On a distant planet with an atmosphere dominated by argon and helium, scientists investigate the respiratory physiology of an alien animal etc.... | alien’s move helium into their blood and exhale more argon than helium |
| In the blood, carbon dioxide is typically found in ____ forms and its presence will cause a ____ of pH. | three-decrease |
| Freedivers, who train to hold their breath for a very long time, would want to _____ their _____. | oincrease their venous reserve and inspiratory reserve volume, decreasing their residual volume |
| You have a prone-position patient whose rib cage is rising and falling; however, air is not flowing through the trachea. Which of the following could be causing the problem? | a. The problem could be attributed to a break has occurred in only the visceral pleura or when the diaphragm contracts, the lungs are not expanding. Since it is a pneumothorax, the Type II cells are producing sufficient surfactant |
| Which of the following is a correct statement about hemostasis? | platelet plug formation is a positive feedback process that aspirin can inhibit, a Vitamin K deficiency will result in decreased fibrinogen activation, and an initial vascular spasm will always bring the sticky ends closer together |
| Four factors were presented in lecture as decreasing oxygen-binding to hemoglobin. A process links them because | their presence indicates where oxygen is being used, the breakdown of glucose produces all four of them, and their presence increases in active tissues |
| has a very tough life and often lets out really big sighs. Correctly occurrences during her sighs are that she uses | both her inspiratory and expiratory reserve volumes, even after her biggest sigh, she has air left in her lungs, and she is expelling more carbon dioxide than with a normal, resting breath |
| Since leeches use chemicals to prevent hemostasis, Sparty bled profusely from the wound. While Brutus bound the wound, he proposed that the leech’s chemicals worked against | fibrin or acted similarly to prostacyclin |
| Correct statements about why hemoglobin binds oxygen | is that binding one oxygen increases the affinity at hemoglobin’s three other oxygen-binding sites, the partial pressure of oxygen is higher in the alveoli than in the blood, and carbon dioxide is not bound to the hemoglobin |
