What are leukocytes classified as?

Leukocytes are classified as white blood cells, which play a crucial role in the immune system by helping the body fight infections and other diseases. They are an essential component of the body's defense mechanism, actively working to identify and eliminate pathogens, such as bacteria and viruses. The classification of leukocytes encompasses various types of cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each serving specialized functions within the immune response.

This classification differentiates leukocytes from other blood components like red blood cells, which are responsible for transporting oxygen, and platelets, which are involved in blood clotting. Plasma cells, on the other hand, are derived from B lymphocytes and are specifically responsible for producing antibodies. Thus, the correct identification of leukocytes as white blood cells illustrates their fundamental importance in maintaining health and combating diseases.
