Of these, leukocytes are primarily involved in the immune response. All formed elements originate in the bone marrow as stem cells (HSCs) that differentiate through hematopoiesis. Granulocytes are leukocytes characterized by a lobed nucleus and granules in the cytoplasm. These include neutrophils (PMNs), eosinophils, and basophils.

Innate immunity, found in all metazoans, provides immediate, non-specific defense through germline-encoded receptors, while adaptive immunity, unique to vertebrates, involves specific responses with memory. It highlights immune cells, pattern recognition receptors (PRRs), and the role of adjuvants in enhancing vaccine responses.
