The next two chapters describe the cells and tissues of the immune system, including hematopoietic stem cells, lymphocytes (T cells and B cells), dendritic cells, macrophages, and other immune cells. The authors discuss the development, structure, and function of these cells and tissues.
This chapter describes the effector mechanisms of immune responses, including the elimination of pathogens by phagocytic cells, the activation of complement, and the production of cytokines.
Chapters 13 and 14 discuss the immune responses to various pathogens, including bacteria, viruses, and parasites, as well as tumors. The authors explain how the immune system responds to different types of pathogens and how these responses can be impaired or evade the immune system.
