Respiratory
Across
- 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
Down
- 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
