1 Describe one way that cytotoxic T cells destroy cells infected with viruses. 2 What is immunity? What role do memory cells play in immunity?

Explanation:

Figure below shows how a cytotoxic T cell destroys a body cell infected with viruses. This T cell releases toxins that form pores in the membrane of the infected cell. This causes the cell to burst, destroying both the cell and the viruses inside it.B lymphocytes are the cells of the immune system that make antibodies to invade pathogens like viruses. They form memory cells that remember the same pathogen for faster antibody production in future infections.
