Surgery Involving the Heart
1. The heart-lung machine (pump-oxygenator) is a valuable addition to the modem operating room. This machine has made it possible to perform many operations on the heart and other thoracic organs which could not otherwise be done. There are several types of machines in use, all of which serve as a temporary substitute for the patient’s heart and lungs.
2. The machine siphons off the blood from the large vessels entering the heart on the right side so that no blood passes through the heart and lungs. The blood is returned to the general circulation for body distribution through one of the large arteries. While passing through the machine, the blood is oxygenated by means of an oxygen inlet, and carbon dioxide is removed by various chemical means. These are the processes that normally take place between the blood and the air in the lung tissue. While in the machine, the blood is also "defoamed" to be sur

Who is smoking a French cigarette
[填空题]By saying "its presence should be felt rather than seen", the author means ______.
[单项选择]If not for the presence of Lionel Messi and Zlatan Ibrahimovic, the FC Barcelena squad that visited Beijing last week would look almost-totally .unfamiliar. Why Because the majority of its normal starting lineup didn’t even bother to con.
Thus, Barca’s Asian tour proved to be another example of dollar profiteering by the European soccer powers. Back in 2003, I paid 180 yuan to watch a game featuring Raul, Ronaldo, Zinedine Zidane, David Beckham, and Luis Figo in Beijing Workers’ stadium. But now, in 2010, my 1, 280-yuan ticket merely let me see Messi and Ibrahimovic for only 45 minutes each.
Most of the 50,000 fans didn’t even know the name of the players kicking the ball around. Only on a few occasions did people cheer, and that was because Messi had the ball.
Every summer around this time, soccer fever reaches its climax in Asian countries, where big-shot clubs take turns playing commercial games. Very often, those games are criticized for their lame performan
