Basophil granulocyte - Definition

Ask a question


Basophil granulocytes represent one of the three types of granulocytes, which are neutral white blood cells. This type is rare (less than 1% of all granulocytes), and play a role in the immune system by neutralizing inflammation, allergies, and infection. They achieve this by means of the chemical molecules they contain, histamine and heparin, which impair blood vessel coagulation. The first also activates an inflammatory reaction, drawing other white blood cells to the site that are designed to fight infection.
