Feedback:
Many body parts are clean, but not sterile. Examples include the skin, mouth, gastrointestinal tract, and upper respiratory tract. These areas are open to the outside and are inhabited by microorganisms at all times. Other body parts are considered to be sterile. Either they do not normally open to the outside (e.g., the abdominal cavity or the ovary) or they do not normally contain any microorganisms. Some areas (e.g., the urinary bladder) are susceptible to infection. The bladder is normally considered to be sterile, even though it is open to the outside.
