The neutrophil is a [[Granulocyte - WikiBlood|granulocyte]] and has a similar development to the other [[Granulocyte - WikiBlood|granulocytes]]. This process is called [[Leukopoiesis#Granulopoiesis|granulopoiesis]] and further details can be found [[Leukopoiesis#Neutrophils|here]].

Three types of granules are present in neutrophils:

Three types of granules are present in neutrophils:

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

*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.

*Finally tertiary granules are either phosphatases or metalloproteinases with the later aiding movement through connective tissue.
