Key Immune Cells in Line Defense Against Pathogens

- Neutrophils: These are the most abundant type of white blood cell and are the first to respond to an infection. They engulf and destroy bacteria and other foreign particles.

- Macrophages: These are large, phagocytic cells that are found in tissues throughout the body. They engulf and destroy bacteria, viruses, and other foreign particles.

- Natural killer (NK) cells: These cells can recognize and kill virus-infected cells and tumor cells.

- Eosinophils: These cells are involved in defense against parasitic infections. They release toxins that can kill parasites.

- Basophils: These cells are involved in the allergic response. They release histamine and other inflammatory mediators when they are activated.
