Textbook Question
Chapter 20, Problem 1AAATB
Some endurance athletes, such as cyclists, engage in the practice of “blood doping,” in which packed red blood cells are transfused into their bloodstream immediately before an event. How might increasing the volume of red blood cells provide an advantage to an athlete? What do you think could be the risks of this practice?

Professional cycling has had much difficulty with cheating. Athletes and team doctors have discovered a variety of unnatural and illegal ways to improve sport performance. Cycling is highly aerobic
which means oxygen is required to produce energy. If you have more red blood cells, you can carry more oxygen to working muscles. There are two methods of illegal blood doping to increase the
number of red blood cells.
1. A few weeks before competition you would have some blood removed into a into a bag like when people give blood. You freeze the blood. Your body will pretty quickly replace the blood to normal
levels. Before the race, you thaw and re infuse the blood. Now you (the athlete) have more than normal amounts of red blood cells. You can now carry more oxygen to yoru working muscles and have
an unfair advantage.
2. You can also inject a hormone called erythropoetin (EPO) to stimulate the bone marrow to make more red blood cells.
What two physiological systems are involved in method…
Endurance athletes sometimes try an illegal method of blood doping called autologous transfusion. Some blood from the athlete is removed well before competition, and then transfused back into the athlete just before competition. (a) Why might blood transfusion benefit the athlete? (b) With time, stored red blood cells become depleted in 2,3-BPG. What might be the consequences of using such blood for a blood transfusion?

- Which of the following statements about red blood cells is false? a. They live about 120 days before being replaced. b. They lack a nucleus and other organelles when they are mature. c. They are replaced when the hormone EPO stimulates stem cells in bone marrow. d. They are replaced as part of a negative feedback loop in which kidney cells monitor blood oxygen levels e.
