Basophil: important in the immune system
What are (meaning)
Basophils are the defense cells of our body, that is, they are one of the subtypes of leukocytes (white blood cells). These cells are very important in the functioning of our immune system.
While fighting an infection in our body, basophils release two important substances. Heparin, which is an important anticoagulant. The other is histamine, which acts as a vasodilator in allergies.
Main characteristics of basophils
- Basophils have granules in their cytoplasm. These granules are large (much larger than the nucleus).
- Possess the ability to release heparin and histamine during the process of fighting infectious agents.
- They are formed in our bone marrow.
- Only between 1% and 2% of the leukocytes in our blood are basophils.
Reference value and leukogram
- A healthy person (over 16 years old) has between 0 and 200 basophils per cubic millimeter of blood. These are considered normal values. Basophils are checked by performing a blood test called a leukogram, which checks the amount of leukocytes in the blood, as well as their subtypes.
