CHAPTER 8: THE MAMMALIAN TRANSPORT SYSTEM
The mammalian transport system is a double circulatory system (combination of pulmonary and systemic circulation). In the test, I demonstrated knowledge of the components of arteries and veins, explained the S-curve, described the function of phagocytes, and described what blood doping was all with just one error. I did not, however, explain myself good enough in question 5 when I was asked how high altitudes affect a human's body and why an athlete would look to that as a way to blood dope. My corrected answer is as follows:
Prolonged exposure to higher altitudes promotes the production of red blood cells. This increases the capacity of an athlete's body to hold oxygen because the exposure to high altitude requires the body to adapt in order to draw in more oxygen to the body. Hence, more red blood cells which are responsible for holding oxygen are produced. The result is the body has an increased capacity to hold oxygen. An athlete would look to blood doping because it increases their stamina at lower altitudes and is also undetectable on steroid tests.
