What are antigens?

Back

Antigens are molecules found on the surface of pathogens that trigger an immune response by being recognized by white blood cells.

Front

What is herd immunity?

Back

Herd immunity occurs when a large proportion of a population becomes immune to a disease, making its spread unlikely.

Front

What is a Neutrophil?

Back

A Neutrophil is a type of white blood cell that plays a crucial role in the immune response by engulfing and destroying pathogens.

Front

What is phagocytosis?

Back

Phagocytosis is the process by which white blood cells surround, engulf, and digest pathogens.

Front

What is the role of antibodies?

Back

Antibodies are proteins produced by B cells that specifically target and neutralize pathogens.

Front

What are the different types of white blood cells?

Back

The main types of white blood cells include Neutrophils, Lymphocytes, Monocytes, Eosinophils, and Basophils.

Front

What is the function of T cells?

Back

T cells are a type of lymphocyte that play a central role in cell-mediated immunity, helping to destroy infected cells.

Front

What is the function of B cells?

Back

B cells are responsible for producing antibodies that target specific antigens on pathogens.

Front

What is the immune response?

Back

The immune response is the body's defense mechanism against pathogens, involving the activation of immune cells and the production of antibodies.

Front

What is vaccination?

Back

Vaccination is the process of introducing a harmless form of a pathogen into the body to stimulate an immune response and build immunity.
