respiratory system vocab test
Across
- 5. amount of air that can be forcibly exhaled after tidal expiration
- 6. a passive process that depends on natural lung elasicity, muscles relax,air is pushed out of the lungs
- 8. amount of air that can be forcibly taken in over the tidal volume
- 11. gas exchange between blood and tissue cells in the systemic capillaries
- 13. the center of the larynx, (vocal chords)
- 17. the total amount of exchangeable air
- 19. every breath someone makes
- 21. gas exchange between pulmonary blood and alveoli, oxygen is loaded into the blood & CO2 is unloaded from the blood
- 22. a chemical process where oxygen is used to make energy from carbohydrates (sugars)
- 23. labored breathing
- 24. the air remaining in the lungs after expiration, allows gas exchange to go on (even between breaths)
Down
- 1. the absence of oxygen
- 2. a dome-shaped muscular partition separating the thorax from the abdomen in mammals. It plays a major role in breathing, as its contraction increases the volume of the thorax and so inflates the lungs.
- 3. a part of emphysema (a respirary disorder), discoloration due to poor circulation and inadequate oxygenation of the blood
- 4. increased respiratory rate, often due to extra oxygen needs (exercising...)
- 7. diaphragm and external intercostal muscles contract, size of thoracic cavity increases,air is sucked into the lungs
- 9. corresponds to the lung parenchyma and includes the respiratory bronchioles, alveolar ducts, and alveoli.
- 10. moving air into and out of the lungs (breathing)
- 12. the soft sounds of air filling alveoli
- 14. (a lipid molecule) coats gas-exposed alveolar surfaces
- 15. the rising levels of CO2 in the blood (acidosis), resulting is faster, deeper breathing- blows off more CO2 to restore back to normal blood pH
- 16. poor oxygen transport to the tissues of the body
- 18. consists of all of the structures that provide passageways for air to travel into and out of the lungs: the nasal cavity, pharynx, trachea, bronchi, and most bronchioles.
- 20. the area where gas exchanges between the alveoli and blood occurs in the lungs
