Basophils are a type of white blood cell that plays a crucial role in your body's immune system. They are essential for defending your body against infections, allergens, and parasites. Basophils are also involved in processes like inflammation and allergies.
They are one of three types of granulocytes, which are white blood cells with granules in their cytoplasm. These granules contain histamine and other chemicals that are released when the basophil encounters an allergen or pathogen. This release triggers an inflammatory response, which helps to fight off the threat.
Here are some key functions of basophils:
- Fighting infection: Basophils help to kill bacteria, viruses, and other pathogens by releasing chemicals that damage the pathogen's cell walls or membranes.
- Responding to allergens: When you encounter an allergen, like pollen or dust mites, basophils release histamine, which causes symptoms like sneezing, itching, and runny nose.
- Promoting blood flow: Basophils release enzymes that help to improve blood flow to the site of an injury or infection. This helps to deliver more immune cells and other resources to the area.
- Preventing blood clots: Basophils release chemicals that prevent blood clots from forming. This is important for keeping blood flowing freely throughout your body.
What is a normal basophil range?
Normally, basophils account for less than 3% of your white blood cell count, with a typical range of 0 to 300 basophils per microliter of blood. A basophil level that is higher or lower than this can indicate certain medical conditions.
In summary, basophils are a vital part of your immune system, defending against infections and allergens while also contributing to blood flow and preventing blood clots.
