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.
The nose is part of the respiratory system, responsible for breathing oxygen into the body. It also plays a role in the immune system by filtering out foreign particles and germs to prevent them from entering the body.
One way the body keeps microbes from entering the body is by the skin, the skin is considered a barrier. That is why when a person gets an injury that breaks the skin the first layer of defence is considered broken. Also the hair and mucous mucus in a persons nose prevent microbes from entering by trapping them . ^ Thats all a lie. This is not a lie at all. It is a very truthful and precise answer, I should know; I am a doctor!!
Mucus is that green stuff inside your nose. It's also inside your throat-it's there to (hopefully) stop viruses, bacteria and anything else that may start a disease getting inside your body. You swallow it and they get destroyed in the stomach. Mucus is the slimy matter secreted by your mucous membranes to provide lubrication and protection from germs. An example is the mucus in your nose.Mucus as in mucus plug, and mucus membrane.
well mucus and hairs in one. when we breath in through our nose the epithiliated cells and mucus trap any pathagons that are in our nasal passages. then when we blow our noses the "snot" contains the pathagons and then we carry on :)
When we get cut, blood flows out of the wound to help cleanse it from debris and bacteria. This is our body's way of protecting us from infection and promoting healing. Blood contains platelets that form blood clots to stop the bleeding.
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.
Pinocchio and dumbo(ears and nose)
I'd assume your skin
Yes, they swell and stop stop harmful bacteria getting into the body, they also filter the body's fluid
it is called Nosteralitis. It is when your nose grows quicker than the rest of your body. There is no cure or operation to stop this process unfortunately.
The skin is only a defense to stop bacteria from entering the body.
Stop wiping your nose with your hand/wrist. Use tissue. When you touch your face you spread bacteria on your face, causing zits/pimples.
their are small hairs in your nose that catch pollens etc... that is why most health professionals promote breathing through your nose instead of you mouth because your mouth has no such defenses.
The job of cilia is to line all along air passages such as, lungs and the nose ect. And is designed to stop dust and bacteria. Also cilia can be damaged or destroyed if are a heavy smoker.
I think you can stop it by just holding your nose when your nose is about to twitch, I have this problem too and its so annoying.
one way is the nose ,the hair and the mucous in a person's noes prevents microbes from getting in by trapping them.
