Hi. Unfortunately, you did not submit the parts of the body to which the question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.
Microorganisms can be aerobic or anaerobic. Aerobics are those that survive in the presence of oxygen and therefore may be present in parts of the cup that have contact with oxygen. Anaerobic organisms are those that do not survive in the presence of oxygen and therefore can only be present in places in the body that do not come into contact with oxygen.
In this case, to answer your question, you need to identify if the parts of the body, that your question presents, come into contact with oxygen or not. This way it is possible to inform if the microorganisms that these parts of the body have are anaerobic or aerobic.
