The immune system is basically a personal army that patrols your body destroying all foreign invaders! the immune system is so complex (you can do whole degrees on it). So to broaden our minds here are some awesome and interesting facts you may not know about your personal protectors.
1) Disease symptoms are sometimes the result of your immune system doing its job.
Yes that's right, your immune system causes some of the symptoms you experience. There is a particular virus that can only reproduce inside your throat cells. What is does is trick the throat cell and hijack its protein making organelles and turns it into a virus factory, spewing out thousand of viruses. In order to eradicate the virus a particular group of white blood cells crudely destroy the cell and others around it. This battle leaves your throat sore and red as more and more cells get destroyed. That's why you get a sore throat when your ill!2) A woman's body tolerates a foetus but in some cases the immune system may try to destroy it.
The immune system works by ruthlessly destroying anything that is not "self" in the body. A growing baby in the womb will be seen by the immune system as a foreign invader like a germ or a virus and will destroy it, (which is the cause of some miscarriages). However there is ways that the foetus avoids this. To find out just follow this link to a great article :http://www.slate.com/articles/double_x/doublex/2012/07/maternal_fetal_bond_why_doesn_t_a_pregnant_woman_s_immune_system_attack_the_fetus_.html
3) The number one way to boost the immune system is to reduce stress
When under stress, cells of the immune system are unable to respond to hormonal control, and consequently, produce levels of inflammation that promote disease. Yeah it's coming up to exam season, y'all need to chill.
4) We have around 50 billion white blood cells in our bodies.
We have two types if white blood cells. They are both made in the bone marrow but from there they part ways. T lymphocytes leave for the thymus gland where they mature. This happens in childhood because as you grow up you loose your thymus gland! Secondly there are the B lymphocytes which patrol your body. The B lymphocytes do the research and find the threat and report to the T lymphocytes who destroy the invaders with military precision! 5) Your White blood cells communicate to each other!
When a foreign invader is found by a white blood cell, it is destroyed. But what the white blood cell does is get the chopped up pieces of the pathogen and carries it on its surface and alerts the other white blood cells of the problem. Its kinda saying " Hey guys, I've found this and it needs destroying can you help me out!". They are called antigen presenting cells!
As always, Seemal
