Chapter 30, Problem 2WIO
Summary Introduction
To determine:
What might be the dangers of having too many red blood cells. If some athletes turn to blood doping to gain an unfair competitive advantage. For example, they may take supplements of erythropoietin, a hormone that stimulates red blood cell production. Why would increasing the number of circulating red blood cells help an athlete.
Concept introduction:
The blood is consists of red blood cells, white blood cells and platelets. Red blood cell contains hemoglobin and is responsible for the transportation of oxygen and nutrients. White blood cells are involves in protection against foreign microorganisms and platelets are involved in clotting.

Hyperglycemia associated with diabetes promotes a prothrombotic state by affecting a number of different steps in the clotting pathway. Which of the following would result in
more rather than less clotting? Check all that apply. The correct answers reflect the effect of hyperglycemia on the clotting pathway!
less conversion of plasminogen to plasmin

abnormally low number of platelets
platelets more sensitive to thromboxane A2
elevated conversion of plasminogen to plasmin
platelets less sensitive to thromboxane A2
low sensitivity to NO and PGI2
increased prothrombin in the blood
increased amount of fibrinogen in the blood
less prothrombin in the blood
abnormally high number of platelets
less fibrinogen in the blood
high sensitivity to NO and PGI2
If a woman has 5 L of blood and she donates 1 pint (about 0.5 L), what approximate percentage is she donating: 1%, 5%, 10%, or 15%? Why do you think individuals below a certain weight (i.e., less than 110 pounds) are not allowed to give blood?

- Several years ago, the deaths of several airline travelers led to the warning about “economic-class syndrome.” The idea is that economic-class passengers do not have as much leg room as passengers in more expensive seats, so they are more likely to sit essentially motionless for long periods of flights-conditions that may allow blood to pool and clots to form in the legs. This condition is called deep-vein thrombosis, or DVT. Given what you know about blood flow in the veins, explain why periodically getting up and moving around in a plane’s cabin during a long flight may lower the risk that a cloth will form.arrow_forwardWhat is the importance of hemostasis(blood clotting)?
