What are white blood cells (WBCs)?

Back

White blood cells, or leukocytes, are cells of the immune system that help the body fight infections and other diseases.

Front

What is the primary function of neutrophils?

Back

Neutrophils are the most abundant type of white blood cells and are primarily responsible for engulfing and destroying pathogens through a process called phagocytosis.

Front

Which type of WBC is known for having a multi-lobed nucleus?

Back

Neutrophils are characterized by their multi-lobed nucleus, which allows for flexibility in movement.

Front

What is phagocytosis?

Back

Phagocytosis is the process by which certain cells, like neutrophils and monocytes, engulf and digest pathogens and debris.

Front

What is the role of monocytes in the immune system?

Back

Monocytes are a type of white blood cell that differentiate into macrophages and dendritic cells, playing a crucial role in the immune response by engulfing pathogens and presenting antigens.

Front

What distinguishes basophils from other WBCs?

Back

Basophils are characterized by their large granules that stain darkly and are involved in inflammatory responses, particularly allergic reactions.

Front

What is the function of lymphocytes?

Back

Lymphocytes are a type of white blood cell that play a key role in the adaptive immune response, including the production of antibodies and the destruction of infected cells.

Front

How do eosinophils contribute to the immune response?

Back

Eosinophils are primarily involved in combating parasitic infections and play a role in allergic reactions.

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 responses, while adaptive immunity involves a specific response to pathogens and develops over time.

Front

What is the lifespan of a neutrophil?

Back

Neutrophils typically have a short lifespan, living only a few hours to a few days, depending on the presence of infection.
