Infections of the urinary tract are common. Urinary tract infections (UTI's) are caused by bacteria that invade the urinary system and multiply, leading to an infection. Women suffer more than men.
Urinary tract consists of the kidneys, greeters, bladder and urethra. The main elements of the system are the kidneys, a pair of purplish-brown organs located below the ribs toward the middle of the back. The kidneys remove liquid waste from the blood in the form of urine, keep a stable balance of salts and other substances in the blood, and produce a hormone that support the formation of red blood cells. Narrow tubes called the greeters carry urine the kidneys to the bladder, a triangle-shaped chamber in the abdomen. Urine is stored in the bladder and emptied through the urethra.
There are three types of urinary tract infections:
Arthritis is an infection of the urethra
Cystitis is an infection of the bladder
Pyelonephritis occurs when bacteria ascend the greeters and infect the kidneys.
