22、ances on their surface.

In 1901 the Austrian doctor Karl Landsteiner classified blood types and discovered that the her

23、editary blood factor is of great importance in blood transfusions because it creates reactions that can threaten the life of newborn infants.The four blood types are known as A, B, AB, and O.

24、ains an antibody directed against substance B, which can be found on the red cells of persons with blood type B. Type B blood contains the opposite things.

25、 is present on the red cells, but the individual is capable of forming antibodies directed against red cells containing substance A or B. If blood type A is transfused into a person with B type blood, anti-A antibodies in the recipient will destroy the transfused A red cells. Because O type blood ha

26、s neither substance on its red cells, it can be given successfully to almost any person. Persons with blood type AB have no antibodies and can receive any of the four types of blood; thus blood types O and AB are called universal donors and universal recipients, respectively.Other hereditary(遗传的) bl
