Chapter 6, Problem 16BS
Delivery of oxygen to muscles is the limiting factor for many athletes. Some try blood doping (injecting oxygenated blood). Others train at high altitude. Both approaches increase the number of red blood cells. Why is doping considered cheating? How would you enforce antidoping rules?

Delivery of oxygen to muscles is the limiting factor for many athletes. Some try blood doping injecting oxygenated blood. Others train at high altitude. Both approaches increase the number of Red blood cells. Why is doping considered cheating? How would you enforce Anti Doping rules?
Which of the following factors would increase the oxygen carrying capacity of the blood?
Question 6 options:
A 50% increase in hematocrit in combination with blood cells that have half the concentration of hemoglobin?
A 20% increase in myoglobin levels.
An increase in temperature.
An increase in pH
none of the above would increase the total amount of oxygen carried by the blood
. Nicotine, one of the components of cigarettes, slows cilia" lining the respiratory tract, causes blood vessels to constrict, and increases heart rate. Another component of cigarette smoke is carbon monoxide. As you have read, carbon monoxide competes with oxygen for binding sites on the hemoglobin molecule found in red blood cells. Analyse the data presented, and describe the potential dangers associated with smoking.

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.
