granulocyte

Granulocytes are a type of white blood cell that play a key role in your immune system's defense against infections. They are called "granulocytes" because they contain small, grain-like structures called granules, which store enzymes and chemicals used to attack germs like bacteria and fungi. There are three main types: neutrophils, eosinophils, and basophils, each identifying and responding to different threats. These cells quickly respond to infection sites, helping to eliminate invaders and trigger inflammation, which is part of your body’s natural healing process.
