White blood cells, also known as leukocytes, are a vital part of the immune system. They help the body fight off infections and foreign invaders.
White blood cells play a crucial role in the immune system by identifying and destroying pathogens, such as bacteria, viruses, and fungi. They also help in the process of inflammation, phagocytosis, and immune response coordination.
White blood cells are produced in the bone marrow through a process called hematopoiesis. They are derived from hematopoietic stem cells, which have the ability to develop into various types of blood cells.
Abnormalities in white blood cell count or function can lead to various health issues, including infections, autoimmune disorders, and leukemia.
