The mucus membrane in the nasal cavity aids in secreting mucus which acts as an adhesive tool in capturing or slowing down external or foreign bacteria and substances from entering your respiratory system particularly your lungs
Mucus
The lining of the mouth is an example of a mucous membrane. Mucous membranes line various cavities in the body and produce mucus to protect and lubricate the underlying tissues.
The stomach has a lining of protective mucus.
Phlegm refers to the mucus lining of bodily cavities, especially that of the respiratory system. Excessive phlegm is associated with colds and influenza and can cause coughing and respiratory distress.
It is usually NOT a volume of mucus that causes the air flow to be blocked. The typical cause is swelling of the lining of the nasal cavities. If mucus from the middle ear is trapped in the Eustachian tube, it can also harbor an infection.
Ciliated epithelium is located in the lining of most body cavities. Some of the cavities that have ciliated epithelium are the lungs, trachea, and nose. Ciliated epithelium serves to keep dust and debris out of the lungs and control the flow of mucus.
The types of membranes lining cavities that communicate with the exterior of the body are mucous membranes. These membranes are found in areas such as the respiratory, digestive, urinary, and reproductive tracts, and they secrete mucus to protect and lubricate the tissues.
The mucus secreting membrane lining all body cavity is derived from endoderm. Together it makes very large surface area. For example surface area of the lungs is 100 square meters and that of small intestine is more than 200 square meters.
Mucus protects stomach lining from gastric acids.
Mucus is a substance produced by the lining of the nasal cavity. This mucus helps moisten and filter incoming air.
The stomach has a special mucus lining that is resistant to stomach acid. If a tiny hole develops in this mucus lining, the result can be an ulcer.
