And the immune system prevents bacteria to go in your blood.White blood cells have alot of protection to kill germs they are police officers in your body for red blood cells.
The immune system is something that mainly keeps us not sick.It is done by our white blood cells killing germs.That is why we are alive for a long time.
THAT IS WHY YOU AREN'T SICK FOR A CERTAIN FOR A AMOUNT OF TIME.The body is so protective that bacteria can only get in by a little cut.
Oh no wonder.
