Answer
White blood cells are an essential part of the immune system. Their primary function is to protect the body against infections and foreign invaders. They achieve this by identifying and attacking pathogens such as bacteria and viruses. Additionally, white blood cells can produce antibodies and remember past infections, which aids in quicker responses to familiar threats.
