Hyow does the how does the Respiratory system stops pathogens from entering the body?

The breathing (or respiratory) system has various adaptation to prevent microbes, which might cause an infection, from entering the lung.
In the nose, hairs filter out dust, and microbes are trapped in a sticky fluid called mucus (boogie) We usually swallow the mucus or get rid of it by sneezing. The mucus also contains a chemical that kills microbes.
BTW: I don't know what i just said there or if the answer fit into the questions???
Sorry, and you can improve or delete my enquiry and let me know! =D

The dust is first caught on the hairs of your nose and sneezed out.
Second defense is partial closure of the vocal cords (actually their primary purpose) which causes turbulence in the incoming air ... since dust is heavier than air the dust tends to end up on the outer part of the flow pattern, which brings it into contact with the mucus lining the breathing passages ... where it is trapped.
And later brought to the throat where it is swallowed (normal), or , if severe, coughed up.

∙ 12y agoBreathing passages don't stop pathogens from entering the body. They provide a way in. That would be like saying how does the tunnel stop the train from passing though the mountain. They do, however, have defenses like mucous and cilia that slow down and reject a lot of unwanted stuff.

∙ 9y agoYour respiratory tract makes mucous. It is very sticky and traps anything that will come into contact with it. You also have tiny "hairs" that beat and push the mucous up and out. You swallow that. The hydrochloric acid in your stomach will kill anything alive. If microbes get further down toward your lungs, your immune system (white blood cells) will also take care of them.

What stops microorganisms from entering the body?
In the human body, the primary line of defence is the skin. The skin stops most of the microbes from entering the interiors of the body. If however, the pathogen is able to gain access into the body, the lymphatic system comes into play. The pathogen is eliminated before it begins to cause any more trouble.
How does the rib cage protect the Respiratory System?
Your respiratory system is the system that brings oxygen onto your body and is mainly associated with the lungs and the windpipe bringing the air down from your mouth. Teh ribs are the bones of your chest that curve round your lungs. They form a cage around the lungs which stops the lungs being crushed. If your lung is pressed flat it cannot take in air. It needs to be inflated like a balloon. Without your ribs every time you came into contact with something it would push the air out of your lungs and wind you.

What does it mean that mucus is a front line defense against infections?
Mucus is a defense against infection as it hepls to catch foreign substances in the airways and other places. (I'm going to use the respiratory system becasue I know the most about it) Mucus is secreted by goblet cells in the lining of the aesophagus, where is is pushed up and out by little cilliated epithelium cells. The mucous acts as an impermeable, sticky barrier - imagine it to be like honey. The mucus helps to catch substances that you have breathed in, such as dust, pathogens, and pollen. The mucus stops this from entering the lungs, and particularly for the pathogens, it stops them from entering the bloodstream. The cillia cells then move the mucous up and out of the aesophagus and into the stomach, where they are killed by your stomach acids. Of course, another way to get rid of it is to cough...
Why is there an initial delay between infection and immune system destroying pathogens?
Your Immune system is usually High, so once it stops smoking that cocaine, it will be better and start destroying them. Its naughty, isnt it?
