    Figure 42.11 Which of the following statements about T cells is false?

    1. Helper T cells release cytokines while cytotoxic T cells kill the infected cell.
    2. Helper T cells are CD4+, while cytotoxic T cells are CD8+.
    3. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only.
    4. The T cell receptor is found on both CD4+ and CD8+ T cells.

    Figure 42.14 Based on what you know about MHC receptors, why do you think an organ transplanted from an incompatible donor to a recipient will be rejected?


    Figure 42.16 The Rh antigen is found on Rh-positive red blood cells. During pregnancy, Rh-negative people can usually carry an Rh-positive fetus to term without difficulty. However, a second Rh-positive fetus may trigger 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?
