Study Notes
Immune System Cells
- B cells are responsible for producing antibodies.
Adaptive Immune System Characteristics
- The adaptive immune system is specific to particular pathogens.
Dendritic Cell Function
- The primary function of a dendritic cell is to present antigens to T cells.
T Cell Types
- Gamma delta T cells are a type of T cell.
- Helper T cells, Cytotoxic T cells and Regulatory T cells are other types of T cells.
- Memory T cells are not a separate type of T cell, but rather a subset of T cells.
Natural Killer (NK) Cell Function
- The primary function of Natural Killer (NK) cells is to recognize and eliminate infected cells or tumor cells.
Innate Immune System Characteristics
- The innate immune system is non-specific to particular pathogens.
- It is the first line of defense against infection.
- It includes physical barriers, such as the skin and mucous membranes, and cells, such as neutrophils and macrophages.
