Explanation / Answer

BITS:

5. ANS: Hypercapnia (Increased level of carbon dioxide in the blood).

6. ANS: Hypoxemia (amount of oxygen in the blood was decreased and it leads to hypoxia).

8. ANS: Changing levels of hydrogen ions, carbon dioxide, and oxygen in the blood trigger changes in respiratory rate.

Matching:

1. CNS -- Controls respirations

2. Cilia— Help move foreign particles and substances from the lungs.

3. Alveolar macrophages--- Phagocytize inhaled bacteria & foreign particles

4. Chemoreceptors--- Sense changes in oxygen or carbon dioxide and signal the brainstem.

5. Mucous membranes--- Secrete mucus to assist cilia to cleanse respiratory tract of foreign particles.

6. Alveolar membrane--- Allows diffusion of O2 & CO2 from alveoli into the bloodstream

7. Trachea--- Transports air with O2 to the lungs

8. Upper airway passage--- Warm & humidify air on its way to the lungs
