A normal leukocyte, or white blood cell, plays a crucial role in the immune system by identifying and combating pathogens such as bacteria, viruses, and parasites. They help protect the body against infections and diseases by recognizing foreign substances, producing antibodies, and coordinating immune responses. Leukocytes also assist in the removal of dead or damaged cells, contributing to tissue repair and overall homeostasis. Different types of leukocytes perform specific functions, including phagocytosis, inflammation, and adaptive immunity.
