Phagocytosis and release of enzymes to kill pathogens.
Key players in adaptive immunity, forming memory cells after infection for faster response upon re-exposure.
Smaller than monocytes with a large, round nucleus and a thin rim of cytoplasm.
Release histamine during allergic responses and inflammation.
Combat parasitic infections and are involved in allergic reactions.
Characterized by granules in their cytoplasm, with three main types: neutrophils, eosinophils, and basophils.
Monocytes, Lymphocytes, and Granulocytes.
Act as antigen-presenting cells (APCs) to activate T-cells and release cytokines to recruit other immune cells.
Essential components of the immune system, involved in protecting the body against infections and foreign invaders.
Largest type of WBC with a kidney-shaped nucleus and abundant cytoplasm with a grayish-blue tint.
B Lymphocytes, which produce antibodies, and T Lymphocytes, which include Helper T-cells and Cytotoxic T-cells.
Differentiate into macrophages and dendritic cells, engulf and digest pathogens and dead cells through phagocytosis.
Provide rapid response to infections and play a role in both innate and adaptive immunity.
They recognize specific antigens and coordinate immune responses.
