White Blood Cell Function

White blood cells (WBCs) are an essential part of your immune system, acting as defenders against infections and foreign substances. They identify and attack bacteria, viruses, and other harmful invaders, helping to prevent illness. WBCs also play a role in managing inflammation and healing damaged tissues. They continuously circulate in your blood and sometimes move to tissues where an infection or injury occurs. By coordinating these responses, WBCs help keep your body healthy and protect you from becoming sick.
