The role of the immune system is protecting the body from pathogens.

The pathogen is an external biological agent that is housed in a certain biological entity, causing or favoring the development of diseases.

Organisms have defense mechanisms that protect them against pathogens such as bacteria, fungi and viruses and that constitute a threat to the life of organisms.

This defensive mechanism in the human body and other living beings is known as the immune system and is made up of a network of white blood cells (lymphocytes and phagocytes) that run through the body.

This system allows, through coordinated physical, chemical and cellular reactions, to keep the organism free of foreign and potentially harmful agents.

These pathogens and elements foreign to the body are called antigens, and their presence in the body triggers a highly specialized reaction to prevent them from spreading or staying in the body.

Therefore, we can conclude that the role of the immune system is protecting the body from pathogens.
