The three ways the respiratory system is protected from harm?
336814
Mucus - The respiratory tract, from nasal cavities to the smallest bronchi, is lined by a layer of sticky mucus. Particles (such as dust and bacteria) which hit the side wall of the tract are trapped in this mucus. \nCilia - found on the epithelial cells move the mucous continually up or down the tract towards the nose and mouth. \nThe mucus and its trapped particles are then swallowed, taking them to the sterilising vat of the stomach.\nLarynx - The entry of food and drink into the larynx is prevented by the structure of the larynx and by the complicated act of swallowing. The larynx is protected by three pairs of folds which close off the airway, preventing food getting into the lungs, which would lead to choking

this may not be the answer you are looking for... but here it is anyway...\n\nthe respiratory system involves providing oxygen for the body. You inhale air which is made of different gases and your lungs absorb oxygen out of the air and you exhale the stuff that isn't absorbed. Oxygen is needed for burning fuel. Every single cell (trillions of them) need this oxygen you just inhaled. How does it get to every single blood vessel? you guessed it! the Circulatory system \n\n... the oxygen rich blood goes to the heart. .. and with every beat gets pumped out in all different directions all over the place and then once the oxygen has been delivered, the spent blood comes back for a refill... this happens many many times per minute. \n\nnow, all this blood would go nowhere without a heart. What is a heart essentially? a big strong muscle that goes and goes and goes for 80 years or more without ever stopping! in addition to this, every move you make, helps blood flow. especially walking, your feet act like mini pumps cuz you step on one foot the blood gets pushed around and then you step on the otehr foot as you walk and it goes on. \n\nAnd of course the nervous system. This has instructions directly form mission control ... your brain. It controls your heart speed, breathing speed, blood flow to different parts of the body depending on which part needs how much at what time and everything. None of these systems could normally work without the other one ... but if your nervous system goes down, your pretty much a vegetable. \n\nI know I just explained what all these different systems do but hopefully it helps you understand better.

Yes, that is the general consensus. But... there are exceptions to every rule. I think if you can maintain a healthy respiratory system the longevity factor will increase. Avoid smoking, chemicals and stay away from situations that could put you in contact with people who may pass influenza to you. I have a cousin who has CF and is now 28 years old and the mother of 3 beautiful, healthy children. I am not saying that she has no health problems, but with the right attitude and mind set you can achieve miracles. Good luck and God Bless You.

The respiratory system is how you breath in and out. In fact, any organism that participates in gas exchange has a respiratory system. In humans and other mammals, the respiratory system consists of the airways, the lungs, and the respiratory muscles that mediate the movement of air into and out of the body.

PROTECT is to keep secure and PREVENT is to stop insecurity.\nexample: you can protect yourself from deseases by taking tablets and also prevent it by eating healthy food.

well if you fell into one the biggest risk is death from inhaling all that lovely methane that is produced in the tank..if that happens then you dont have to worry about this other stuff LOL...but if you fell in with a scba on (what firefighters wear) then you'd have to worry about a multitude of bacteria's such as C-diff,MRSA,VRE,hepatitis the list goes on and on......

The main protection is simple soap and water to protect you and the pateient.  It is the most effective way of preventing transmission of disease... but you must do it after every patient!  Good luck.
