Quizplus · Accepted Answer

Macrophages are a type of white blood cells that engulf and digest foreign particles, including bacteria and debris in the respiratory tract. T-cells and B-cells are involved in the immune response but not specifically in the removal of foreign particles in the respiratory tract. Blastocysts are early-stage embryos and are not involved in the immune system.
