White Blood Cells
White blood cells, also known as leukocytes, are a type of blood cell that plays a crucial role in defending the body against infection. They are produced in the bone marrow and mature in the lymphatic system. White blood cells can be divided into two main types based on their appearance and function:
Lymphocytes:
B lymphocytes, also known as B cells, recognize specific antigens on the surface of infected cells and activate the immune response.
T lymphocytes, also known as T cells, recognize viral antigens and activate the immune response.
Granulocytes:
Neutrophils are the most common type of white blood cell, phagocytosing bacteria, viruses, and other pathogens.
Eosinophils are involved in defending against allergic reactions and parasites.
Basophils release histamine and other inflammatory mediators, promoting healing and defense.
White blood cells are vital for the body's immune response. They can quickly identify and respond to foreign substances, such as pathogens, through mechanisms like phagocytosis and antigen recognition. This ability allows the body to eliminate infections and maintain overall health
