<p>Two types of granules are present in basophils:

*Azurophilic granules which are present in all granulocytes and contain acid hydrolases and other enzymes.  

*Azurophilic granules which are present in all granulocytes and contain acid hydrolases and other enzymes.  

*Specific granules contain heparin, histamine, leukotrienes and some lysosomes. Heparin has anti-coagulative capabilities and is also involved in assisting lipid uptake from the blood after meals. Histamine causes vasodilation.</p>

<p>Fc receptors on the basophil surface binds with IgE formed during allergic reactions and causes them to degranulate. The vasoactive substances released from the granules causes vasodialtion allowing for the infiltration of other leukocytes i.e. [[Neutrophils#Movement|neutrophil diapedesis]].</p>
