1. What are the normal values of O2 in the blood?

80-100 mmHg

2. What is the normal pH of the blood?

7.36-7.44

3. What is the job of the nose?

filter and humidify air

4. What is the job of the epiglottis?

closes to avoid the flow of swallowed food and liquid into the trachea

5. what is the job of the larynx?

provides the capability of speech

6. What is the flow of air through the components of the lungs?

Bronchi -> bronchial -> alveoli (business end)

7. What is exchanged from the blood with the alveoli?

oxygen flows from the lungs to the blood, and CO2 comes from the blood to the alveoli as gas to be expired air

8. What are the three definitions of respiration?

pulmonary ventilation, gas transport, and cellular respiration

9. What is pulmonary respiration?

the movement of air in and out of the lungs

10. What is gas transport?

the exchange of gases across various barriers via diffusion
