Assignment:

1. Oxygen Transport

a. What are the 2 ways oxygen is transported in the blood?

b. Which of the 2 oxygen transport methods above is detected by the peripheral chemoreceptors?

c. Please draw the Hemoglobin saturation curve, and mark on the axis where oxygen is loaded and unloaded.

2. How is carbon dioxide transported in the blood?

3. How would your saturation curve for oxygen change if your blood was acidic and the temperature was high?

4. Why is carbonic anhydrase important?

5. If my blood was acidic, but I had a low amount of 2,3 BPG, would I have a normal hemoglobin saturation curve? Why?

6. At altitude with low oxygen partial pressures, we would hyperventilate as we switch to peripheral chemoreceptors. Hyperventilation then lowers carbon dioxide levels in the blood. Our red blood cells create 2,3 BPG to fix this issue. If the individual at altitude was also very cold, what would happen to the Hemoglobin saturation curve?

7. If I hyperventilate, I would decrease the amount of carbon dioxide (hypocapnia). What would this do to my hydrogen ion concentration (pH)? 8. What buffers are present in the body?

9. If there is less bicarbonate available, what would this do to the pH of the body?

10. If you were on a carbohydrate free diet, but you had fat present in your diet, what would this do to your pH? If this changes your pH, what is the molecule that causes this?

11. Camilla was stung by a bee, and then had an allergic reaction. Fortunately, they had an epi pen in their bag!

a. If Camilla forgot the Epi pen to bronchodilate her bronchioles, what would this do to her blood gases?

i. Would there be a metabolic acid? What would it be?

ii. Would there be a respiratory acid?

iii. Would the body be able to compensate?

12. During Pulmonary edema, there is often a decrease in oxygen with a decrease in carbon dioxide. What is the metabolic acid associated with pulmonary edema? How would the body compensate?
