At the same time, dissolved molecules will also participate to take away the nutrients needed to grow for invading microorganisms.
- The second barrier, much stronger, is the specific immune system consisting of specific attack antibodies to kill invading subjects, B lymphocytes, T lymphocytes, and cytokines. To kill the virus, the most important agents are T lymphocytes, namely CD8 + T cell and CD4 + T cell. These cells destroy the virus, limit the reproduction of new viruses, from which the body will recover. However, the specific immune system does not respond immediately as the non-specific immune system, depending on the specific case, maybe several days.
People with good immune systems are hard to get sick and can recuperate more easily, even if they may not be cured, in many cases. In contrast, people with weak immune systems will need to be very careful with infectious diseases, infections, … To improve the immune system, everyone needs to supplement nutrition, improve physical strength, healthy living, get an optimistic spirit,…
