ANSWER THE FOLLOWING QUESTIONS: 1. Central chemoreceptors are located in the __________ and they detect changes in __________ and __________. Of these, the concentration of __________ is the most closely monitored. Respiration is increased when the levels of __________ become too high. 2. Peripheral chemoreceptors are located in the __________ and __________ where they monitor blood __________, __________ and __________ concentrations. When arterial O2 concentration falls below __________ mmHg, higher respiration will be triggered. 3. What happens to arterial PCO2 and PO2 during the breath hold? 4. Which factor (O2 or CO2) has a stronger effect on BH time? (Hint: central chemoreceptors detect changes in what?) 5. Define the following terms: - Hyperventilation: - Hypoventilation: - Hypercapnia: - Hypoxia:

14. If a person hyperventilates, what will happen to the following in the blood? 13. What ion directly stimulates the central chemoreceptors? 12. What type of sensors inform the respiratory control center? 11. Where is the respiratory control center located at? 10. CO2 transport as bicarbonate ions: CO2 binds with water to form acid. The catalyst for this reaction is The acid mentioned above then dissociates into ions and ions. The reaction occurs in the opposite direction at the lungs so that CO2 can be released. 9. When CO2 binds to hemoglobin, it is called pCO2, pH

If the pH, PO2, and PCO2 of arterial blood do not change during the light to moderate phase of the progressive test, what are the signals to the respiration center that drive breathing in proportion to the workload? A) stretch receptors located in the lungs B) neural input from higher brain centers C) feedback from chemoreceptors located in the carotid bodies D) feedback from chemoreceptors located in the aortic bodies
