Question

These directly attack the foreign cells of an incompatible skin graft.
A)antigens
B)antibodies
C)helper T cells
D)cytotoxic T cells
E)effector B cells

Accepted Answer

Cytotoxic T cells directly attack foreign cells, such as those of an incompatible skin graft.

Answer: A
 Antigens are molecules on the surface of foreign cells that trigger an immune response, which can lead to the activation of cytotoxic T cells.

Answer: B
 Antibodies are proteins produced by B cells that can recognize and bind to specific antigens on the surface of foreign cells, marking them for destruction by other immune cells.

Answer: E
 Effector B cells are activated B cells that produce large quantities of antibodies targeted against specific foreign cells or molecules.

Answer: C
 Helper T cells play a crucial role in activating and coordinating the activities of other immune cells, including cytotoxic T cells, in response to foreign cells or molecules.
