“Think about you immune system He said: “It’s not a black and white switch, but an army of super soldiers.” “You have an army, a navy, an air force, and a marine corps. They all have their own weapons and all have their own skills.”
As far as the appearance of your body is concerned, let’s break it down: the fluid in your nose, mouth and even eyes Full of antibodiesLi said that when they are exposed to the virus, they are like the first line of defense. Li said: “These are called IgA.” Immunoglobulin A. “They will stop a lot of viruses, and your body will clear them and get rid of them.” For example: When you blow your nose into the tissues, the viruses will be cleared along with the mucus.
But if the virus manages to sneak in, other super soldiers must go to work: “This is not just a universal antibody,” Li said. “This is the other part of the innate immune system. Intruders must be studied. They must be monitored… They sent some troops to observe carefully. They magnified it. They took a picture and sent it back to the home team and said, “Do you know? This does not look good. I think we need to be able to respond. ‘”
These soldiers (the soldiers who took snapshots of the virus secretly taken through the first antibody system) are called T cells. Li said that every time a “bad guy” successfully crosses the first line of defense, your T cells will remember the virus in order to tag it to other parts of your immune system when it needs to respond. He said: “They put it in the iCloud of the immune system.”
If the virus accumulates, your immune system will send killer cells to attack the threat, and once you resolve the infection, these cells (antibodies) will decrease. Li said: “Unless absolutely necessary, your body will no longer produce any antibodies.” “But T cells tend to stick because they always carry the virus in the memory bank.”
