What type of natural defense mechanisms are in place to prevent urinary tract infection? Be specific.

Solution

The urinary tract infections are reported to be the most common infection after common cold and flu. since the urinary tract is most of the time exposed to bacteria, are prone to catch then infections. So the immunological barriers or we can say, natural barriers are present to fight the infections caused in the urinary tract.

Immune cells communicate with each other so as to fight the UTI , as these infections can also arise as a result of invasion of intestinal bacteria into the urethra.

Main barrier to fight the UTI are Neutrophulls, which keep circulating in the blood and rush to the site of infection, and kill the bacteriaby either phagocytosis or by reeleasing some toxins. and the function of neutrophils is regulated by macrophages, so that the damage of neighbouing healthy cells is minimum.

Other natural barrier is urine, which washes out the bacteria from the urethra and prevents the adherence of infecting bacteria in the urinary tract.Kidney also produces some proteins which contains mannose and helps preventing the infectitious bacteria adherence to the tract.
