Leukocytes, commonly known as white blood cells (WBCs), are a crucial component of the immune system. Their primary function is to detect and combat infections,
foreign substances, and disease-causing organisms.
There are several types of leukocytes, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each playing a unique role in immunity.
High WBC count may indicate infection or inflammation; low count may suggest immune deficiency.
Information Booster:
• They are produced in the bone marrow and circulate in blood and lymph.
• Phagocytosis is a key mechanism used by WBCs to destroy pathogens.
• Normal WBC count: 4,000 to 11,000 cells per microliter of blood.
• Neutrophils are the most abundant and first responders to infection.
• Lymphocytes (B and T cells) are key to producing antibodies and immune memory.
