Genes from both parents determine the surface antigens on a person's RBCs. For this reason, a child's blood type can differ from that of either parent. During pregnancy, when fetal and maternal circulatory systems are closely intertwined, the mother's antibodies may cross the placenta, attacking and destroying fetal RBCs. The resulting condition is called hemolytic disease of the newborn (HDN). Some forms are quite dangerous and others so mild as to remain undetected. The sensitization that causes HDN usually takes place during delivery. Bleeding at the placenta and uterus exposes an Rh-negative mother to an Rh-positive fetus's Rh antigens. This event can trigger the production of anti-Rh antibodies in the mother. The first Rh-positive infant is not affected because these antibodies are not produced in large amounts until after delivery. However, a sensitized Rh-negative mother will produce massive amounts of anti-Rh antibodies in response to a second Rh-positive fetus. These antibodies attack fetal RBCs, producing a dangerous anemia. In addition to Rh, what are the other main surface antigens on red blood cells that determine blood type?

D only

O only

A and B

D and C

A and B

The primary function of white blood cells is to

help defend the body against pathogens
