næsegangene

Næsegangene, also known as nasal passages or nasal cavities, are the hollow spaces within the nose. They are lined with a mucous membrane that produces mucus, which helps to trap dust, pollen, and other airborne particles. The nasal passages are also covered in tiny hairs called cilia, which sweep the mucus and trapped particles towards the throat, where they can be swallowed or coughed out.

The primary functions of the næsegangene include filtering, warming, and humidifying inhaled air before it reaches the lungs. This process protects the delicate tissues of the respiratory system from irritation and infection. Additionally, the nasal passages play a crucial role in the sense of smell, as they contain olfactory receptors that detect different scents. They also contribute to speech by acting as resonating chambers.

Various conditions can affect the næsegangene, such as sinusitis, which is inflammation of the sinus cavities connected to the nasal passages. Allergies can also cause congestion and irritation within the nasal passages, leading to symptoms like sneezing, runny nose, and itchy eyes. The health and proper functioning of the næsegangene are essential for overall respiratory health and well-being.
