The Immune system and the Urinary system
The Immune system is vital for protecting the urinary system from painful diseases. Called Urinary tract infections, The Infections are usually caused by a bacteria known as E. coli. This bacteria normally lives in the colon, but if it makes it into the urinary tract, it is bad news. The infection normally starts in the urethra. if the immune system doesn't stop it, and gets no help from antibiotics, then the bacteria will continue along the urinary tract. Next to be infected is the bladder. By now, the immune system really needs outside help to deal with the infection. next, E. coli goes to the kidneys and infects that. By this time, there is no possible way for your immune system to defeat this bacteria on its own. As you can see, sometimes the immune system needs help to fight against diseases, especially if they get into delicate systems such as the urinary system.
