What is the oxyhemoglobin dissociation curve, and what factors
affect the curve to shift right or left. Additionally, explain what
type of effect stored (banked) blood have on the oxyhemoglobin
dissociation curve.

using the oxyhemoglobin dissociation curve describe the
relationship between the O2 delivery cascade and arterial and
venous O2 content. Provide one (1) physiological reason that might
lead to a reduction in arterial O2 content (CaO2) and one (1)
reason there would be a decrease in venous O2 content (CvO2).
1-what is partial pressure? Explain it’s role in gas exchange?
2- Describe the factors affecting gas exchange. Apply these
factors to the efficiency of a tracheal system, gills, lungs in
mammals, lungs in birds?
What is the Law of Demand?
What factors cause the Demand Curve to shift? There are
five.
What is the difference between a change in Demand and a change
in Quantity Demanded?
Draw graphs illustrating 1) an increase in Demand and 2)
increase in Quantity Demanded? Label your axis! . If you can’t
figure out how to post graphs, describe what they would look
like.
What causes a change in Quantity Demanded?
What is the difference between a Normal Good...
Which of the following actions will cause the equilibrium to
shift such that the partial pressure of NO gas will increase?
2NO(g) + O2(g) ⇌ 2NO2(g) ΔH = −13.1 kJ
Increase the pO2(g)
Increase the volume
Lower the reaction temperature
Decrease the pNO2(g)
If the pulmonary capillary partial pressure of a gas
equilibrates with that in the alveolus before the blood leaves the
capillary (gas diffusing from the alveolar space to the
capillary):
a. its transfer is said to be perfusion limited
b. its transfer is said to be diffusion limited
c. increasing the cardiac output will not increase the amount of
of gas diffusing across the alveolar-capillary barrier
d. increasing the alveolar partial pressure of the gas will not
increase the amount...
The equilibrium water vapor pressure table gives the partial
pressure of water when the gas is 100.% saturated with water vapor.
If the gas you collected was actually only 85% saturated with water
vapor, calculate the percent error in the number of moles of N2
collected in Part I.
mass nano2 = .111g
v of wet n2 gas = 37.9 ml
partial pressure n2 = .966 atm
moles n2 collected = 1.53*10^-3
moles n2 expected = 1.61*10^-3
