Three types of granules are present in neutrophils:

*Primary granules (azurophilic) are present in all [[Granulocytes|granulocytes]] and contain myeloperoxidase which creates anti-bacterial compounds, acid hydrolases and defensins.

*Secondary granules (specific) are the most numerous type and contain complement activators and enzymes e.g. collagenases.
