Immune system and infection prevention – basic principles
How it works
The immune system protects the body from pathogens such as bacteria, viruses, and fungi. It consists of various cells (e.g. white blood cells), organs (e.g. spleen, lymph nodes), and molecules (e.g. antibodies). There is an innate (nonspecific) and an acquired (specific) immune response. Infection prevention includes measures such as hygiene, vaccination, and quarantine to prevent the spread of diseases.
Note
The immune system recognizes and fights pathogens through various defense mechanisms; infection prevention prevents the entry and spread of pathogens.

An example
What task do antibodies have in the immune system?
Antibodies bind to pathogens and mark them so that they can be recognized and eliminated by other immune cells. They are part of the specific defense.
