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

How would paralysis of the diaphragm alter inspiration? It would prevent contraction of the intercostal muscles It would prevent inhalation because the intrapleural pressure would not change It would decrease the intrapleural pressure and allow more air to enter the lungs It would slow expiration because the lung would not relax.
