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.
One of the current major areas of research in heart transplants is the use of pig hearts for human transplants. Since pig and human hearts are virtually identical anatomically, researchers feel that it can make hearts available to everyone that needs one. Should the organs of pigs (or any other animals) be used to preserve the lives of humans? Why or why not?
