NASAL PASSAGES Meaning and Definition

  1. Nasal passages, also known as nasal cavities or nasal airways, are the channels through which air enters and exits the nose. They form a vital part of the respiratory system, being responsible for filtering, warming, and moistening the inhaled air before it reaches the lungs.

    The nasal passages are located behind the nose and are divided into two symmetrical sides by a structure called the nasal septum. The walls of the nasal passages are lined with a mucous membrane that contains numerous tiny hair-like structures called cilia. These cilia serve to trap and filter out dust, pollen, bacteria, and other foreign particles present in the inhaled air, preventing them from reaching the lungs.

    Within the nasal passages, there are also specialized cells known as goblet cells that produce mucus, a sticky substance that further helps in trapping foreign particles and moisturizing the air. This mucus, along with the cilia, helps to prevent drying of the delicate tissues lining the nasal cavities and assists in preventing infections.

    The nasal passages also play a role in the sense of smell. Located within the nasal mucosa are olfactory receptors, specialized cells that detect odor molecules present in the air. These receptors send signals to the brain, allowing us to perceive various scents and flavors.

    In summary, the nasal passages are the air-filled channels located behind the nose that serve several essential functions, such as filtering, warming, and moisturizing inhaled air, as well as playing a crucial role in the sense of smell.
