The immune system is a system of organs that exists in vertebrate animals and unites organs and tissues. They protect the body from diseases, identifying and destroying tumor cells and pathogens. The immune system recognizes many different pathogens – from viruses to parasitic worms. It distinguishes them from their own cell biomolecules. The recognition of pathogens is complicated by their adaptation and the evolutionary development of new methods for successfully infecting the host organism.
The ultimate goal of the immune system is to destroy the foreign agent. They may be a pathogen, a foreign body, a poisonous substance or a regenerated cell of the organism itself. This is achieved by the biological individuality of the organism.
In the immune system of developed organisms, there are many ways to detect and remove foreign agents: this process is called the immune response. All forms of the immune response can be divided into innate and acquired reactions. The main difference between them is that the acquired immunity is highly specific to a particular type of antigen. This allows you to quickly and efficiently destroy them in a second collision. Antigens are molecules that are perceived as foreign agents and cause specific body reactions. For example, people who have suffered from chickenpox, measles, and diphtheria often have lifelong immunity to these diseases. In the case of autoimmune reactions, a molecule produced by the body itself can serve as an antigen.
Some substances produced by the immune system actively influence the functioning of the central nervous system.
