In mammals, which is the most common type of agranulocyte?

Lymphocytes are indeed the most common type of agranulocyte in mammals. They play a vital role in the immune system, primarily in the adaptive immune response. Lymphocytes can be divided into subtypes, including T cells, B cells, and natural killer (NK) cells, each having distinct functions. T cells are involved in cell-mediated immunity, B cells produce antibodies, and NK cells help in targeting and destroying virally infected cells or tumors.

The predominance of lymphocytes in the white blood cell population is significant for immune surveillance and reaction to specific pathogens. Their ability to remember past infections, through memory cells, enhances the body's ability to respond more effectively to previously encountered pathogens, highlighting their central role in maintaining immune health.

In contrast, the other options represent different types of white blood cells that are present in lesser quantities. Eosinophils and basophils are involved in allergic reactions and responses to parasitic infections but are considered granulocytes due to the granules they contain. Monocytes, though larger and playing a key role in phagocytosis and serving as precursors to macrophages, are less numerous than lymphocytes in the bloodstream. Thus, lymphocytes are identified as the most prevalent type of agran
