Nose Function - Sense of Smell
We love your nose. It is an amazing tool, and one that will find olfactory bliss from our work.
The nose is an important organ in the respiratory system that helps you breathe by filtering, warming, and moisturizing the air you inhale. It also plays a role in your sense of smell.
Inside the nose, there are two passages called nasal cavities. The nasal cavities are lined with a thin layer of tissue called the mucous membrane, which produces mucus. The mucus helps to keep the nasal passages moist and also traps any foreign particles, such as dust or pollen, that you inhale.
Hairs called cilia, which are found on the mucous membrane, help to move the mucus and trapped particles towards the back of the throat, where they can be swallowed or coughed out.
At the back of the nasal cavities, there are small openings called sinuses that lead to the throat. The sinuses produce mucus as well and help to moisten and warm the air you breathe.
In addition to its respiratory functions, the nose also contains a small patch of nerve cells called the olfactory epithelium, which is responsible for the sense of smell. When you inhale, the odor molecules in the air bind to special receptors on the olfactory epithelium, which sends a signal to the brain that allows you to detect the smell.
Overall, the nose plays a vital role in helping you to breathe and in your sense of smell.
