[h] Immunology Flashcards

[i] Master this session in just 5 minutes.

[q] Which type of immune system?

Nonspecific immune response that provides the body’s early line of defense against microbial invaders, with limited diversity, no memory cells, immune cells involved are Neutrophils, macrophages, monocytes, dendritic cells, natural killer (NK) cells?

[q] Which type of immune cell?

– Location: Bloodstream.

[f]IE5ldXRyb3BoaWxzLg==[Qq]

[q] Which type of immune cell?

– Location: Bloodstream.

– Identification: Bilobed nucleus, large pink granules.

– Function: Defense against parasitic infections by antibody-dependent cellular cytotoxicity (ADCC), a method of killing that depends on the ability of the immune cell to recognize specific antibody bound to a cell and trigger the death of that cell without the use of complement.
