NASAL PASSAGE Meaning and
Definition
-
The nasal passage is the complex system of air-filled cavities and passages located within the nose. It serves as a channel for the exchange of air between the external environment and the respiratory system. The nasal passage begins at the nostrils and extends towards the back of the throat.
The nasal passage is divided into two main sections by a vertical structure called the nasal septum, which is composed of bone and cartilage. Each section of the nasal passage consists of three main regions: the vestibule, the respiratory region, and the olfactory region.
The vestibule, located near the entrance of the nostrils, is lined with coarse hairs and mucus-secreting cells that help to trap larger particles and prevent them from entering deeper into the respiratory system.
The respiratory region of the nasal passage contains numerous blood vessels and mucous glands. It is responsible for humidifying and warming the inhaled air, as well as filtering out finer particles, such as dust and pollen.
The olfactory region, situated at the upper part of the nasal passage, contains specialized olfactory receptors that recognize and transmit smell sensations to the brain.
Overall, the nasal passage plays a crucial role in respiratory function by filtering, warming, and humidifying the air we breathe, as well as contributing to our sense of smell.
