A 12 y old boy complained of tiredness and not feeling well. His mother noticed that his eyes and skin were kind of yellowish. She took him to the clinic for examination. A CBC and a urinalysis were done. Results were as follows:
Chemical analysis​​​Physical analysis
pH 5.0​​​​​dark urine (brownish)
All negative except bilirubin
Microscopic unremarkable
CBC: Slightly elevated leukocytes with lymphocytosis
RBC normal

A mountain climber ascends to an altitude where the partial pressure of oxygen in the atmosphere is very low.

a. What happens to the climber’s ventilation rate?

b. Which chemoreceptor (oxygen or carbon dioxide/pH) would cause this change in ventilation rate at high altitude? Your answer should reflect that you know the stimuli for change in ventilation rate under different conditions

c. What happens to plasma concentrations of carbon dioxide after a period of time hyperventilation?

d. What happens to plasma pH after a period of time at high altitude? Your answer should reflect that you understand the relationship between CO2 levels and pH.

e. What happens to levels of erythropoietin in the blood after a period of time at high elevations? Your answer should include the stimulus for the release of EPO

f. How does a low concentration of oxygen in the alveoli affect the state of contraction of pulmonary arterioles?

g. Explain why pulmonary edema is a symptom of altitude sickness. Your answer should demonstrate your understanding of fluid exchanges at the capillary level
