The nose produces muccus (aka snot, bogies etc) and this traps the bacteria (you can sometimes notice you get black snot after being in a polluted environment). The cellia cells (nostril hairs) then transport the contaminated muccus to the throat where it is swallowed and taken to the stomach where the low ph number (high acidity) of the stomach kills of the microbes. Hope this was helpful.

You should speak to a doctor about getting your nose to stop twitching. Nose twitching can be a sign of nerve damage. It also can happen when people are tired or stressed out.

Boogers are usually harmless and just a mixture of mucus, dirt, bacteria, and other particles. However, excessive nose-picking can lead to nosebleeds, infections, or irritation of the nasal passages. It's best to avoid eating them as it can introduce bacteria into your system.
The nasal cavity is filled with hairs, which help filter the atmospheric air as you inhale. After air passes through the nostrils it is pulled through the nasal concha, which are folds of tissues that secrete mucus (snot). The mucus also traps bacteria.

Sneezing, also called sternutation, is an involuntary, sudden and violent rush of air out through the nose and mouth. The body takes this action to get rid of irritating or harmful objects in the nose. Sneezing aids the body, but can be harmful to other people. For example, the nose fills with congestion that contains germs when a person has a cold. Sneezing helps clear the nose. But unless the sneezer covers the mouth and nose, the germs escape into the air and may infect others.
Stop wiping your nose with your hand/wrist. Use tissue. When you touch your face you spread bacteria on your face, causing zits/pimples.
