Is trachea part of the respiratory system?
Yes, but they're not identical. The mucus lining the respiratory system is used as a dirt (well, dust) trap. The mucus lining the digestive system acts as a barrier to the digestive juices (so that you don't try to digest yourself [see 'ulcers' as example of failure]).

What function does mucus have on the gastrointestinal tract?
In the stomach, the stomach acid is there to digest protein. Your stomach, as is mucus, is made of protein. So, your stomach produces mucus to sacrifice instead of the stomach muscle/protein. The mucus is continually being digested by the acid, but it is also continuously being produced at the same rate as its digestion. The mucus also protects the inner lining of the digestive system against abrasive objects you may have eaten. Lubrication? Need I say more than that mucus is slippery so the food slides more easily.
How is mucus coating and ulcer related?
Mucus is carbohydrate based. It is not affected by the pepsin. Once this barrier is broken, pepsin attack the stomach wall to form the ulcer. You give acid lowering agents to lessen the efficiency of the pepsin.
What is an example to physical barrier to infection?
One of these natural barriers is the skin, which protects the internal organs from damage caused by diseases, as well as harmful chemicals and radiation from the sun. The nasal hairs in the nose and sticky mucus along the windpipe also helps prevent dieseases by filtering the air. If some irritants get into the nose, the person will cough to shift the mucus down into the throat to be swallowed. The mucus will then be transfered to the stomach so that the microbes can be killed by its acid.
