Pre-Lab Questions:
“1. Research the process of erythropoiesis, and explain the role erythropoietin plays. Why is this
a popular “doping” drug for athletes? “
Erythropoiesis is the method by which erythrocytes, the red blood cells are created. It is moved by
low levels of oxygen in circulation, which the kidneys discover making it produces the
hormone erythropoietin, it energizes multiplication and differentiation of red blood cells
precursors, which makes it increase the production of red blood cells.
“2. How would the hemoglobin content differ in a person living in Philadelphia (Elevation: 39
feet) compared to someone living in Denver (Elevation: 5280 feet)? Why? “
m
er as
The person living in Denver has an altitude higher in elevation than the person living in Philadelphia.
co
Which means the person living in Denver has higher content because red blood cell production will

increase to compensate for the lower oxygen supply in Denver due to the higher altitude.
