Ch. 16 - The Respiratory System

4. The process of exchanging oxygen, carbon dioxide, and other blood solutes with the external environment.
7. This membrane covers the lungs and thoracic cavity.
9. The total amount of air inside the lungs at certain phases of the respiratory cycle.
13. Where are the cartilaginous rings located in the airway?
15. The nerve that controls the diaphragm and intercostal muscles.
16. A temporary cessation of breathing for greater than 20 seconds.
17. Nares, Septum, & Conchae are located.
18. The four stages of _________ include pulmonary ventilation, external gas exchange, gas transport in the blood and internal gas exchange.
19. Respiratory depression is the abnormal retention of CO2 in the blood.
20. Vocal Cords, Epiglottis & Glottis are located
21. This cavity contains the heart, lungs, esophagus, trachea, and thymus.
24. What muscle separates the thoracic and abdominal cavity?
26. Located on either side of the mediastinum and are made up of soft tissue that brings in oxygen and releases carbon dioxide.
27. Located between the bronchi and alveoli.
28. The volume of air remaining in the lungs after maximum forceful expiration
30. The degree of struggle with airflow through the respiratory tract during inspiration and expiration

1. intercostal Muscles and the diaphragm are known as the _______.
2. Needed during lung expansion so that the alveoli sac open.
3. Causes acidosis due to respiratory depression and retaining CO2.
5. When a person takes more than 20 breaths per minute.
6. The cartilaginous rings are located.
8. What are the abducens, trigeminal and the accessory nerves.
9. The lower respiratory tract begins here with in the thorax.
10. The process of diffusing oxygen from the blood, into the interstitial fluid and into the cells.
11. The state of breathing quickly reduces the amount of CO2 in the blood.
12. This cavity is divided into two sections allowing air to move into the body, the passageway filters, humidifies and warms the air.
14. Nasopharynx, Oropharynx, & Laryngopharynx are located.
22. How does oxygen travel in the body in the red blood cell?
23. A state of reduced CO2 causing acidosis requires someone to breathe in a brown paper bag to increase CO2 levels.
25. Foreign bodies frequently get lodged here.
29. This is where gas exchange occurs in the lungs.
