Webb17 jan. 2024 · White blood cells, also known as leukocytes, are immune cells that circulate in the blood and lymphatic system. Neutrophils – main action against bacterial and fungal infections. Monocytes – main action against bacterial infections. Eosinophils – main action against parasitic infections. Basophils – responsible for responses to allergens. WebbThe mast cell, another granulocyte, is similar in appearance and function. Both cell types store histamine, a chemical that is secreted by the cells when stimulated. However, they arise from different branches of hematopoiesis, and mast cells usually do not circulate in the blood stream, but instead are located in connective tissue.
