7. What is the pressure of oxygen within the alveoli at the peak of inspiration, just before expiration, relative to that of atmospheric air? Less than atmospheric air The same as atmospheric air Greater than atmospheric air 8. Where are the central chemoreceptors located (the ones involved with regulating respiratory drive)? Hypothalamus Cerebral cortex Brain stem Spinal cord How might central and peripheral chemoreceptors compare with regard to their responses after hypoventilation occurs? Decrease in carbon dioxide is detected by both central and peripheral chemoreceptors Increase in carbon dioxide is detected by both central and peripheral chemoreceptors Increase in oxygen is detected by both central and peripheral chemoreceptors Decrease in oxygen is detected by both central and peripheral chemoreceptors 10. What is the name of the nerve that innervates the diaphragm, allowing our nervous system the ability to alter ventilation rates? Vagus nerve Sacral nerve Radial nerve Phrenic nerve

Asthma is a very common disease. It is characterized by widespread narrowing of the bronchioles and formation of mucus plugs, producing symptoms of wheezing, shortness of breath, and coughing, and is caused by the release of factors during an allergic response. Explain why the narrowing of bronchioles, rather than that of the larger bronchi, is the source of the airflow restriction, and why inhaling dilating agents can bring relief during an asthma attack.
