What is the function of white blood cells?

White blood cells (WBCs) are responsible for protecting the body against infections and harmful microorganisms. They are an important part of the immune system.

These cells identify and destroy bacteria, viruses, and other foreign substances that enter the body. Some white blood cells produce antibodies, while others directly attack pathogens.

White blood cells also help remove damaged cells and support the body’s defense mechanisms during illness and injury.

Their protective role is essential for maintaining health and preventing diseases.
