both

Is a natural killer cell innate or adaptive?

both

neutrophil

granulocyte that phagocytizes bacteria and fungi

monocyte

agranulocyte that acts like precursor to macrophages causing inflammation or phagocytosis

dendritic cell

agranulocyte that phagocytizes bacteria presenting antigens to T cells

in skin, respiratory, and intestinal mucosa

natural killer cell

adaptive

True or False: Is a cytotoxic T lymphocyte innate or adaptive?

adaptive

True or False: Is a T regulatory cell innate or adaptive?

adaptive

plasma cell/B cell

agranulocyte that recognizes antigens producing antibodies

T helper cell

agranulocyte that binds MHCII molecules to antigen-presenting cells

secretes cytokines

cytotoxic T lymphocyte

agranulocyte that binds MHCI molecules to recognize and kill specific “nonself” cells

T regulatory cell

agranulocyte that destroys incorrectly recognized “self” cells
