Respiratory

4. chemoreceptors located in medulla stimulated by hydrogen ion
5. gas exchange that occurs when oxygen moves from blood into tissues and wastes move into blood
9. amount of air moving in and out during relaxed breathing
11. process of food or fluids entering the respiratory tract
13. ease of expansion of thorax and lungs
14. exchange of air between the atmosphere and the alveoli
15. blood is about 70% saturated with oxygen
16. excessive rate of breathing
18. decreased hydrogen ions and increased bicarbonate ions in body
20. respiratory rate and depth are increased causing increased exhalation of carbon dioxide
21. volume of air expelled by maximum exhalation after maximum inhalation
22. chemoreceptors located in carotid and aorta which respond to extremely low blood oxygen levels
25. decreased arterial blood level of oxygen
26. placement of fist below xiphoid process and umbilicus causes air to force object blocking airway
28. carbon dioxide is transported as this in the blood
29. amount of air is insufficient to meet metabolic requirements
30. temporary cessation of breathing for short periods of time

1. determines how easily air flows down the pressure gradient
2. reduces water surface tension allowing alveoli to expand
3. cells take in oxygen to breakdown nutrients
6. amount of air left in lungs after maximum exhale
7. continuous double membrane that covers lungs
8. this can affect the respiratory rate and cause an increase
9. total volume of air that can be contained in lungs after maximum inhalation
10. amount of fluid needed in 24 hours to mobilize secretions
12. pressure of gas within a mixture
17. this is initiated by cilia moving mucous and foreign bodies to be expelled
19. uses abdominal muscles to help expel air
23. increased hydrogen ions in body
24. elevated arterial blood level of carbon dioxide
25. decreased oxygen levels in the tissues
27. gas exchange that occurs when oxygen moves from the alveoli into the blood and CO2 moves into alveoli
