Nasal Cavity: What is It and What Does it Do?

Nasal Cavity: What is It and What Does it Do?

‘Nasal cavity’ is a physiological term that refers to each cavity of the two sides of the nose. Sometimes, it can also refer to the two cavities found in the nose combined. Anyways, the nasal cavity is the uppermost part of our respiratory system - a relatively large and air-filled space just above and behind the nose. It is the continuation of the nostrils - the reason why humans have two of them.

The whole cavity is divided into its two parts by nasal septum to be connected with the two nostrils, which then offers a passage for the inhaled air to be transported to the other parts of the respiratory tract.

Despite being so integral to our respiratory system, we know little to nothing about the nasal cavity. So, today, let’s find out some of the most interesting facts about it from below.

What are the Functions of a Nasal Cavity?

The nasal cavity is the one that is responsible for our sense of smell. It has a few other important functions too, which are warming and humidifying the inhaled air, traps and removes pathogens and other particulate matter from the inhaled air, and finally, draining and clearing the lacrimal ducts and paranasal sinuses.

Do All Humans Have the Same Nasal Cavity?

Don’t sniff at the question, please! If people have different-sized noses, it is also valid to wonder whether they have different-sized nasal cavities. Anyways, without going into the scientific details, it can be said that women and men have different-sized nasal cavities just like noses. In general, men have a nose more than women and the same applies to cavities.

What are the Common Diseases of Nasal Cavity?

Nasal cavities can be infected by different viruses, fungus, and bacteria. There are also some nasal cavity tumours - both malignant and benign. Nasal mucosa, Nasal polyps, and Rhinitis are some of the other severe nasal cavity conditions.
