310 Review Sheet 24 18. + Atelectasis is a collapsed lung. Explain how a pneumothorax might result in atelectasis and what should be done to restore the negative pressure of the pleural cavity. 19. Pectus excavatum is a condition in which the anterior thoracic cage is caved inward because of abnormal development of the sternum and ribs. What effect would you expect this condition to have on vital capacity, and why?

11. Blood CO₂ levels and blood pH are related. When blood CO₂ levels increase, the pH increases. Explain what changes would occur in the blood's pH if the breathing rate were increased or decreased. 12. Length of breath holding after hyperventilation: Why does hyperventilation produce apnea or reduce respiratory rate? 13. Observations for rebreathing breathed air: Why does rebreathing breathed air increase respiratory rate? 14. What was the effect of running in place (exercise) on the duration of breath holding? Explain: 15. Record your data for the test illustrating the effect of respiration on circulation: Radial pulse before beginning test. Radial pulse after testing Relative radial pulse force before beginning test. Condition of neck and facial veins after testing Explain: Review Sheet 24 /min Relative radial pulse force after testing 309 /min 3. increase in blood pH. 4. decrease in blood pH. Did it appear that CO₂ or O₂ had a greater effect on modifying the respiratory rate? 17. Where are sensory receptors sensitive to changes in O₂ levels in the blood located? sec 16. Do the following factors generally increase (indicate with I) or decrease (indicate with D) the respiratory rate and depth? 1. increase in blood CO₂ 2. decrease in blood O₂
