Question

Explain in your own words what happens when a virus gets in your body. Use the following words in your explanation: Vaccine, Antibody, Immune System, Memory Cells.

Answer 1

ExplaThe first line of defence is your body's skin and mucous membranes.

If pathogens manage to get through these barriers, they encounter special white blood cells present in your bloodstream. There are different types of white cells, called neutrophils (polymorphs), lymphocytes, eosinophils, monocytes, and basophils.

White blood cells travel in your bloodstream and react to different types of infection. These might be caused by bacteria, viruses or other pathogens. Neutrophils engulf bacteria and destroy them with special chemicals. Eosinophils and monocytes also work by swallowing up foreign particles in your body. Basophils help to intensify swelling (inflammation).

Inflammation is part of your body's immune response. Damage to your tissues causes the release of different chemicals into your blood. These chemicals make blood vessels leaky, helping specialised white blood cells get to where they are needed. They also attract neutrophils and monocytes to the site of the injury. This helps to protect against a bacterial infection developingnation:

Answer 2

if the virus enters a body the immune system will try to attack the virus with the antibodies but our body is not prepared to face the virus, if you become infected with it it will bring all the consequences that the virus brings but the memory cells will recognize the virus and if it contracts the virus again the immune system would recognize it and attack it with antibodies prepared for virus. Scientists are investigating for a vaccine that makes a kind of weak version of virus so that the immune system can attack them easier because it will be much weaker than virus so that the memory cells will recognize them so that if you contract the original coronavirus, the immune system would recognize it and attack it with antibodies prepared for virus.
