What is the meaning of basophils?
Basophils are white blood cells with large dark blue granules. They are involved in allergic reactions
What granulocyte has the smallest granules?
Basophils have the smallest granules among granulocytes. These granules contain chemicals involved in inflammatory responses and allergic reactions.
What is the structural characteristic of a eosinophils?
They contain a bilobed nucleus and their granules stain red, due to the eosin dye. Plus, the granules themselves look almost crystalline. Don't get them confused with basophils which also have a bilobed nucleus BUT basophils granules do not stain well (and when they do they stain blue) in comparision.

What group constist of granulocytes?
Granulocytes include neutrophils, eosinophils, and basophils. They are characterized by the presence of granules in their cytoplasm and play a role in immune responses, such as fighting infections and allergies.
Are meta chromatic granules present in staphylococcus?
Metachromatic granules (volutin) are not made by staphylococcus.
Does a basophil have a nucleus?
Yes Basophils contain large cytoplasmic granules which obscure the cell nucleus under the microscope.The nucleus usually has 2 lobes.
What is the life span of basophils?
Basophils have a relatively short lifespan of only a few hours to a few days in circulation. They are responsible for mediating allergic responses and inflammation by releasing histamine and other chemicals from their granules.
Which white blood cell type has granules that stain dark purple in response to alkaline dye?
Basophils are the white blood cell type that has granules that stain dark purple in response to an alkaline dye. These granules contain substances such as histamine and heparin, which play a role in inflammatory reactions and allergic responses.
Where is the anticoagulant heparin produced in?
Heparin is released by mast cells and basophils of the blood and present in many tissues, especially in the liver and lungs.
What are two main categories of leukocytes?
The two categories are granulocytes and agranulocytes. Granulocytes have visible cytoplasmic granules. Examples of granulocytes include neutrophils, eosinophils, and basophils. Agranulocytes have no visible cytoplasmic granules. Eamples of agranulocytes include lymphocytes and monocytes.
Function of the mast cells.?
Mast cells and basophils produce the histamine, which antihistamines block. The cytoplasm of a mast cell is filled with granules containing histamine and heparin. Histamine, released after injury or infection, stimulates local inflamation. People often take antihistamines to reduce cold symptoms. Basophils, blood cells that enter damaged tissues and enhance the inflammation process, also contain granules of histamine and haparin.
