How does the Circulatory System and the Immune System Interact?
During the immune response, blood vessels around infected areas widen to deliver more white blood cells to infected areas. White blood cells are needed for fighting infections. Examples of white blood cells are Phagocytes, Macrophages, T cells and B cells. They swallow and devour pathogens whole to fight them off. Other White Blood Cells identify pathogens and create antibodies to fight the infection. White blood cells are created in the bone marrow, they then go to the thymus to become a strong White Blood Cell. White blood Cells are delivered through the body via circulatory system to fight off infection. This all saves the circulatory system and the rest of the body from harmful infections.
