The nose is a prominent structure between the eyes that serves several important functions. It is the entryway to the respiratory system and contains the olfactory organ, which provides our sense of smell. It also serves to condition, filter, and warm the air we breathe in. It also has other functions such as cleansing the air we inhale and providing a protective barrier against harmful particles. These are just a few of the functions of your nose.
The respiratory region of your nose performs all of the above functions, and many more. The respiratory region heats, filters, humidifies, and protects the air we breathe. It also houses receptors that give us odor and protects our respiratory tracts. Columnar epithelium is a liner in the nasal cavity that secretes mucus and assists in mucociliary clearing of aerosolized particles. It also facilitates drainage of air from adjacent paranasal sinuses. The olfactory recesses in the superior portion of the nasal cavity receive odor-bearing particles, which are transmitted to the olfactory bulb and olfactory lobes.
The nasal cavity is a complex structure with three distinct elevations that hang over air passages. The olfactory portion of the nasal cavity sits above the uppermost concha, and the respiratory part is lined with a moist mucous membrane. Mucus from the membrane wall helps trap bacteria and debris that cause bad smell. The nose serves all these functions, except for swallowing. If you have trouble breathing, the nose can be a source of problems.
The septum is a piece of firm cartilage and bone that runs down the center of the nose. It separates the two nasal cavities, each one containing a nasal cavity and sinuses. The sinuses make mucus that helps us breathe. There are also folds in the nose called turbinates. The turbinates moisten the air after we breathe and aid in nasal drainage. Head and neck cancer can develop in the nasal area, causing symptoms such as sneezing and runny nose.
The nasal conchae increase airflow in the nasal cavity. They also increase the mucosal surface area exposed to air. Going from low to high altitude increases the erythrocyte count. Although the nose performs all of these functions, the ones listed above are just a few. If you suffer from a cold, it is important to have the sinuses cleaned. When your nose is blocked, your sinuses will become secondary sites of infection and your blood may have a high level of mucous.
The nasal cavity contains two cavities that are separated by the septum. The nasal cavity contains two cavities, the nares and the palatine bones. The roof of the mouth is formed by the palatine bone. The soft palate is part of the nasopharynx, and closes the nasopharynx to prevent food particles from getting trapped in the back of the nose. These cavities contain several structures that help us breathe and speak.
