What special features do white blood cells have to do their job?

Answer 1

White blood cells (WBCs) possess several special features that enable them to effectively perform their roles in the immune system. They have the ability to move through blood vessels and tissues, allowing them to quickly reach sites of infection or injury. Many WBCs can recognize and remember specific pathogens, enabling a faster and more efficient response upon subsequent exposures. Additionally, certain types of WBCs can engulf and destroy pathogens through a process called phagocytosis, while others produce antibodies to neutralize infections.
