1. If PO2 is 80 mmHg in the capillaries and PO2 is 40 mmHg in the interstitial tissues, will O2 diffuse into the capillaries or into the interstitial tissues? Why?

2. PCO2 is 45 mmHg in the pulmonary capillaries and PCO2 is 40 mmHg in the lung tissue. Which direction across the respiratory membrane will CO2 flow? Why?

3. PCO2 is 45 mmHg in the interstitial fluids and PCO2 is 40 mmHg in the capillaries. What direction across systemic capillary membranes will CO2 flow? Why?

4. PO2 is 120 mmHg in the aveoli and P O2 is 20 mmHg in the pulmonary capillaries. Which direction across the respiratory membrane will O2 flow? Why?

5. PO2 is 55 mmHg in the interstitial fluids and PCO2 is 48 mmHg in the capillaries. Which direction across the systemic capillaries membranes will O2 flow? Why?

6. PCO2 is 55 mmHg in the cells and PCO2 is 48 mmHg in the interstitial fluid. Will CO2 flow from cells to fluid or from fluid to cells? Why?

7. PCO2 is 45 mmHg in the capillaries and PO2 is 40 mmHg in the alveoli of the lungs. Which direction across the respiratory membrane will CO2 flow? Why?

8. PO2 is 40 mmHg in the interstitial fluids and PO2 is 100 mmHg in surrounding cells. Will O2 flow from fluids to cells or cells to fluids? Why?

9. PO2 is 120 mmHg in the aveoli and PO2 is 20 mmHg in the pulmonary capillaries. Which direction across the respiratory membrane will O2 flow?

10. Whose law is the Law of Partial Pressures? briefly explain this law.

11. The lower the PO2 of the tissue cells, the ________________________(higher or lower?) the dissociation of O2 from the hemoglobin molecules in the capillaries.

12. If your Vital Capacity is 5200ml and your TV is 450ml and your ERV is 1000ml, what is your IRV Is this IRV within the norm for healthy males? Healthy females?

BONUS: If your TV = 480ml and IRV = 1800ml and ERV = 750 ml, what is your VC? Are you most likely a male or a female?
