More about immunity
What is immunity?
Simply put, immunity is "a system that removes things that are alien to the body". This may seem like a very simple task, but it has a huge impact on our complex body.
Immunity has reassuring role that removes things that are alien to the body. But if it work wrong it expose us to danger.
Why is immunity necessary?
On the contrary, let's assume that there is no immunity. Without immunity, our body cannot resist the invasion of external microbes.(This could be a bacterium, virus and parasite). Bacteria and viruses use our bodies to try to increase their numbers.No resistance means that you provide them with a place to proliferate. Eventually, the growth of these bacteria and viruses and the poisons they release will cause our bodies to wear out and die. To protect us from such horrific conditions, organisms on the Earth have evolved their immune systems.
