Front

What are phagocytes?

Back

Phagocytes are a type of white blood cell that engulfs and digests foreign particles, bacteria, and dead or dying cells.

Front

What role do macrophages play in the immune system?

Back

Macrophages are large phagocytes that consume pathogens and dead cells, and they also help activate other immune cells.

Front

What type of white blood cell is primarily associated with allergic reactions?

Back

Basophils are primarily associated with allergic reactions and release histamines.

Front

What is the function of T cells in the immune response?

Back

T cells are responsible for directly killing infected host cells and regulating the immune response.

Front

What is the difference between innate and adaptive immunity?

Back

Innate immunity is the body's first line of defense, providing immediate but non-specific protection, while adaptive immunity develops over time and provides specific responses to pathogens.

Front

What is the significance of memory cells in the immune system?

Back

Memory cells are long-lived cells that remember past infections, allowing for a faster and stronger response upon re-exposure to the same pathogen.

Front

How do antibodies function in the immune response?

Back

Antibodies bind to specific antigens on pathogens, marking them for destruction by other immune cells.

Front

What is the role of neutrophils in the immune system?

Back

Neutrophils are the most abundant type of white blood cell and are the first responders to sites of infection, where they engulf and destroy pathogens.
