20、 Types of Blood You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. Howev er, special care must be taken in selecting new blood for you. If the blood is t oo different from your own, the transfusion could kill you. There are four basic types of blood: A, B, AB, and O. A simple test can ind icate a person’s blood type. Everybody is born with one of these four types of b lood. Blood type, like hair color and height, is inherited from parents. Because of substances contained in each type, the four groups must be transf used carefully. Basically, A and B cannot be mixed. A and B cannot receive AB, b ut AB may receive A or B. O can give to any other group; hence, it is often call ed the universal donor. For the opposite reason, AB is sometimes called the univ ersal recipient. However, because so many reactions can occur in transfusions, p atients usually receive only salt or plasma ( liquid ) until their blood can be matched as exactly as possible in the blood bank of a hospital. In this way , it is possible to avoid any bad reactions to the transfusion. There is a relationship between your blood type and your nationality. Among Europeans and people of European ancestry, about 42 percent have type A while 45 percent have type O. The rarest is type AB. Other races have different percenta ges. For example, some American

The Romans also built great pipes under the ground to carry away the sewage. In Romes these sewa ge pipes (sewers) are still used today; it is 2,000 years old. The Roman Emperor s even set up a government Wealth service. They built the first great public hos pitals in Europe, and they paid doctors to look after poor people. Then the Roman Empire fell to pieces, these civilised methods of treatment d isappeared from most of Europe, for more than a thousand years. People went back to the old ways. They lived in dirty conditions which helped to cause diseases; and they asked God to cure the diseases. They shut up mentally sick people in p risons. Or they burnt them alive because they were supposed to have magic power. But the work of the Greek and Roman doctors was lost. Over a thousand years ago, the Arabs moved into many of the Mediterranean countries. They took big par ts of the old Roman lands. They translated the Greek and Roman medical books int o Arabic. Arab doctors themselves made many new discoveries. When civilization at last came back to Europe, men once again translated the Greek and Roman works on medicine into Latin. Slowly very sloppily European doc tors discovered again the things that the Greeks and Romans had known so long ag o. Slowly, they began to make new discoveries. They found out more about the way the body works the way our blood goes round our bodies, the way our nerves send messages from our brain
