The areas of the body that we consider sterile are those part of the body that are not exposed to the environment. Our skin is home to vast numbers of several different types of microbes as or the openings that lead deep within. All of the organs inside our body should be considered sterile with the exception of the lumen of the G.I. tract. While the intestines are an organ inside us it houses materials that where once exposed the the environment and is home to microbes as well. Now there are times that bacteria can penetrate our organs and become infected but under normall circumstances you consider them sterile.
None
A sterile field is considered contaminated if you turn your back to the sterile field because the sterile items are considered out of vision.
Sterile means free of living organisms, so a sterile field is an area that is completely clean of any living organisms. This is the kind of field that surgery is done in to prevent infection. A non-sterile field is an area that though clean, may have living organisms such as bacteria on it.

The four sterile sites in the human body are the brain, blood, cerebrospinal fluid, and the internal tissues and organs. These sites are typically free from normal microbiota and are considered to be sterile environments within the body.
The inside of the bladder is considered one of the most sterile parts of the human body due to its ability to constantly flush out bacteria and other microorganisms through urination.
Urine is typically sterile when it leaves the body, but it can become contaminated with bacteria if not handled properly. It is considered a waste product that the body eliminates to get rid of excess water and chemicals. Additionally, urine can be a source of germs and should be disposed of properly to avoid contamination.
If a sterile field becomes "contaminated" with a sterile solution, the field remains sterile.

The brain and spinal cord have no normal flora, as they are considered sterile environments in healthy individuals.
PRINCIPLES 1. Only sterile items are used within the sterile field. 2. Gowns are considered sterile only from waist to shoulders level in front and the sleeves. 3. Tables are sterile only at table level. 4. Persons who are sterile touch only sterile items or areas; persons who are not sterile touch only unsterile items or areas. 5. Unsterile persons avoid reaching over a sterile field; sterile persons avoid leaning over an unsterile area. 6. Edges of anything that encloses sterile contents are considered unsterile. 7. Sterile field is created as close as possible to time of use. 8. Sterile areas are continuously kept in view. 9. Sterile persons keep well within the sterile area. 10. Sterile persons keep contact with sterile areas to a minimum. 11. Unsterile persons avoid sterile areas 12. Destruction of integrity of microbial barriers results in contamination. 13.Microorganisms must be kept to an irreducible minimum
A bronchoscopy would typically be classified as a clean-contaminated wound, as the procedure involves entering the respiratory tract, which is considered a normally sterile area of the body that could potentially introduce contaminants during the procedure.
