Final answer:
Antimicrobial substances are produced by neutrophils, monocytes, and mast cells and are also stored in granules. B cells play a role in destroying bacteria, inactivating toxins, and producing antibodies. Neutrophils and monocytes are examples of granulocytes, while lymphocytes are agranulocytes responsible for adaptive immune response.
Step-by-step explanation:
Antimicrobial substances are produced by neutrophils, monocytes, and mast cells but are also produced in and stored in granules. B cells destroy bacteria and inactivate their toxins. They also produce antibodies. Neutrophils and monocytes are examples of granulocytes that contain granules in their cytoplasm, while lymphocytes are agranulocytes that are responsible for adaptive immune response.
