In everyday speech, the phrase "good immunity" or "weak immunity" is often found. Under the word "immunity" people understand something that protects us from various diseases: viruses, bacteria, infections, etc. What exactly is behind this, what this immunity looks like, many do not even think about. The mechanism of developing immunity lies in the synthesis of special cells, each of which performs its function. Thus, microphages eat microbes and destroy them in themselves, B-lymphocytes - produce antibodies and remove foreign genes from the body, T-lymphocytes kill microorganisms, neurophiles devour foreign matter, but they themselves are destroyed, the action of eosinophils is directed at parasites, etc. If a person is immune to various diseases, then the immune system works without failures. Frequent infectious diseases indicate that some of its links are inoperable and must be activated.
