Figure 17.17 The Rh antigen is found on Rh-positive red blood cells. An Rh-negative female can usually carry an Rh-positive fetus to term without difficulty. However, if she has a second Rh-positive fetus, her body may launch an immune attack that causes hemolytic disease of the newborn. Why do you think hemolytic disease is only a problem during the second or subsequent pregnancies?

Figure 17.17 After initially binding an antigen to the B cell receptor, a B cell internalizes the antigen and presents
it on MHC class II. A helper T cell recognizes the MHC class Il- antigen complex and activates the B cell. As a
result, memory B cells and plasma cells are made.
The Rh antigen is found on Rh-positive red blood cells. An Rh-negative female can usually carry an Rh-
positive fetus to term without difficulty. However, if she has a second Rh-positive fetus, her body may launch
an immune attack that causes hemolytic disease of the newborn. Why do you think hemolytic disease is
only a problem during the second or subsequent pregnancies?
