What is a "leukocyte"?
A leukocyte, also known as a white blood cell, is a crucial component of the immune system in the human body. These specialized cells are responsible for defending against infections and diseases. Leukocytes circulate in the bloodstream and can migrate to tissues, where they perform various functions such as phagocytosis, antibody production, and immune regulation. They play a crucial role in the body's defense mechanisms, recognizing and eliminating pathogens, foreign substances, and abnormal cells. Leukocytes are essential for maintaining overall health and immune system function.
