White blood cells leukocytes differ from red blood cells in several key ways. They are larger and less numerous than red blood cells. In addition, they have nuclei and organelles, whereas red blood cells and platelets do not. Most leukocytes spend a short time circulating in the blood, and the rest of the time, they can be found within lymphatic tissues or organs like the thymus or spleen. They are often secretory vessels.

The different types of granular myeloid white blood cells —neutrophils, basophils, and eosinophils—are named based on the type of stain that makes their granules most visible. Each type of granular myeloid white blood cell has granules with different chemical contents that help these cells respond to different types of pathogens.

Neutrophils are the most numerous granulocytes, making up a large percentage of the leukocytes found in human blood. In neutrophils, the granules are small and evenly distributed, and they appear pale lilac in color when they absorb basic or acidic dyes.

Like other granulocytes, the nuclei of neutrophils are segmented into several connected sections, or lobes. Because of this, granulocytes are often referred to as polymorphonuclear leukocytes PMNs. Most neutrophils have between two and five lobes that vary in shape. Neutrophils play a significant role in the innate immune response, often being the first, and most numerous, type of white blood cell to arrive at sites of infection or inflammation.

There is a single nucleus, which is multilobed, and can have between 2 and 5 lobes. The chromatin in the nucleus is condensed. This means that there isn't protein synthesis. There are few organelles in the cytoplasm. Neutrophils are the commonest type of white blood cell found in a blood smear. Function: Neutrophils are born in the bone marrow. They circulate in the blood for hours, and then enter the tissues. They are motile, and phagocytic and will destroy damaged tissue and bacteria.

They self destruct after one burst of activity. This picture shows an eosinophil in a blood smear. You can see that eosinophils only have two lobes to their nucleus. These cells have large acidophilic specific granules - these stain bright red, or reddish-purple. These granules contain proteins that are 'destructive' and toxic. Function : These cells are born in the bone marrow, and migrate from the peripheral blood system after a few hours, into loose connective tissue in the respiratory and gastointestinal tracts.

They phagocytose antigen-antibody complexes. They also produce histaminase, and aryl suphatase B, two enzymes that inactivate two inflammatory agents released by mast cells. A high eosinophil blood count may indicate an allergic reaction.
