Guida verificata passo dopo passo1
Understand the role of white blood cells in the immune system: White blood cells are responsible for defending the body against infectious agents like bacteria and viruses.
Identify the types of white blood cells: Common types include neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with specific functions.
Focus on neutrophils: These are the most abundant type of white blood cells and are the first responders to microbial infection, especially bacteria and viruses.
Recall the functions of other options: Platelets are involved in blood clotting, fibroblasts in tissue repair, and erythrocytes (red blood cells) in oxygen transport, none of which destroy pathogens.
Conclude that the white blood cells that destroy bacteria and viruses are neutrophils, based on their role as primary phagocytes in the immune response.
