Heart and Blood Vessels
PRE-LAB QUESTIONS
1. Research the process of erythropoiesis, and explain the role erythropoietin plays. Why is
this popular “doping” drug for athletes?]
Erythropoietin is produced by the kidneys and stimulates the production of red blood cells.
Athletes may use erythropoietin as a doping drug because it increases the number of red blood
cells, which leads to improved oxygen delivery to the muscles. This can enhance endurance
and performance.
2. How would hemoglobin content differ in a person living in Philadelphia (Elevation: 39
feet) as compared to someone living in Denver (Elevation: 5,280 feet). Why?
They would have a higher hemoglobin content because the body naturally produces more red
blood cells at higher altitudes to compensate for lower amounts of oxygen concentration in the
air.
