Answer 1

Answer:

Neutrophils

Granular leukocytes, also called granular or granulated white blood cells, contain granules in their cytoplasm. Granules are tiny sacs that contain various enzymes, compounds and other components that are used to defend against pathogens, reduce inflammation and destroy cells

Neutrophils, eosinophils, and basophils are granular leukocytes. Neutrophils are the most abundant granular leukocytes and account for 60-70% of all leukocytes. They form an essential part of the innate immune system, with their functions varying in different animals. neutrophils contain a nucleus divided into 2–5 lobes. Neutrophils are a type of phagocyte and are normally found in the bloodstream. The cytoplasm of neutrophils contains numerous purplish granules called azurophilic or primary granules that contain microbicidal agents.They are formed from stem cells in the bone marrow and differentiated into subpopulations of neutrophil-killers and neutrophil-cagers. They are short-lived and highly motile, or mobile, as they can enter parts of tissue where other cells/molecules cannot. Neutrophils may be subdivided into segmented neutrophils and banded neutrophils (or bands)

whereas agranular leukocytes include lymphocytes and monocytes, when monocytes leave the circulation they differentiate into macrophages.Macrophages comes under agranulocytes.
