Question
Directions: Choose the one best answer to each item. Items 1 to 5 refer to the following information. In the 1800s blood transfusions were practiced; blood was transferred from one person to another. Sometimes the transfusions were miraculously successful, while at other times persons experienced pain, tingling sensations, and often death. In 1901 a scientific basis was recognized for successful transfusion of blood. It was realized that blood had to be divided into groups, and only certain types could be transfused successfully to a given individual. If an incompatible blood type is transfused into a person, the blood cells will clump together in a reaction called agglutination. Agglutination is due to a reaction between antigens and antibodies in the blood. An antigen refers to any substance that produces an immune response; usually the body reacts by producing antibodies. The antibodies fight off the antigens, which are considered invading substances. The best-known system of antigens in the blood is the ABO system. The surfaces of red blood cells of blood types A, B, and AB contain certain substances that act like antigens. The safest transfusion of blood takes place when the donor and recipient have the same type of blood. Otherwise, two of the most critical factors are the antigens contained in the donor's blood and the antibodies contained in the recipient's blood plasma. Antigens and antibodies should not oppose one another. If the red blood cells containing these antigens are transferred into a person whose blood plasma contains antibodies against them, clumping occurs. Blood Red Blood Type Cells Contain A B AB O Plasma Contains antibodies against B antibodies against A no antibodies antibodies against A and B A antigens B antigens A and B antigens no antigens 1.
