Basophil

 Basophils are the least common form of granucloyte in the White blood cell family. They circulate the body in the blood stream and can be recruited into a tissue when needed.

These cells have large granules in their cytoplasm, hence why they fall into the granulocyte family. They have a multi-lobed nucleus, usually it's 2 lobes. The basophil cell stores histamine, a vasodilator, in the granules which is secreted in response to a foreign antigen. It is connected to inflamatory responses, and in particular allergic responses.
