Immune Cells

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

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

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

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

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

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

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

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

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

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