Detailed explanation-1: -A healthy immune system can defeat invading disease-causing germs (or pathogens), such as bacteria, viruses, parasites-as well as cancer cells-while protecting healthy tissue. Understanding how the immune system works and how we can help protect our bodies is essential to the fight against the COVID-19 pandemic.
Detailed explanation-2: -On a basic level, autoimmune disease occurs because the body’s natural defenses-the immune system-attack the body’s own healthy tissue. Researchers have several ideas about why this happens. When the body senses danger from a virus or infection, the immune system kicks into gear and attacks it.
Detailed explanation-3: -In general, your body fights disease by keeping things out of your body that are foreign. Your primary defense against pathogenic germs are physical barriers like your skin. You also produce pathogen-destroying chemicals, like lysozyme, found on parts of your body without skin, including your tears and mucus membranes.
Detailed explanation-4: -Antibodies. Antibodies help the body to fight microbes or the toxins (poisons) they produce. They do this by recognising substances called antigens on the surface of the microbe, or in the chemicals they produce, which mark the microbe or toxin as being foreign. The antibodies then mark these antigens for destruction.
