In a normal peripheral blood, which statement is true about leukocytes?

Leukocytes, or white blood cells, play a crucial role in the body’s immune response, and they are comprised of several different types of cells, including neutrophils and lymphocytes. Neutrophils are the most abundant type of white blood cell and are essential for combating infections, particularly bacterial infections. Lymphocytes are vital for both the adaptive and innate immune responses, including the production of antibodies and the destruction of virus-infected cells.

In a normal peripheral blood sample, the presence of both neutrophils and lymphocytes reflects the diversity of immune functions that leukocytes perform. This combination allows for a robust response to a variety of pathogens and helps maintain overall health. The various types of leukocytes, including basophils, eosinophils, monocytes, neutrophils, and lymphocytes, collectively interact to form a functional immune system capable of protecting the body from disease. Thus, the inclusion of neutrophils and lymphocytes is a fundamental aspect of leukocyte composition in the blood.
