näsess

Näsess is a Swedish term that translates to "nostril" in English. It refers to either of the two external openings of the nose. Each nostril leads to a nasal cavity, which is part of the respiratory system. The nostrils play a crucial role in breathing, filtering inhaled air, and detecting scents. They are lined with fine hairs called vibrissae, which help to trap dust and other particles before they can enter the respiratory tract. The moist lining within the nostrils also warms and humidifies the air, making it more suitable for the lungs.

The appearance and size of nostrils can vary significantly among individuals and are often considered a feature of facial structure. In some contexts, "näsess" might be used colloquially, though its primary meaning remains the anatomical one. The olfactory receptors responsible for our sense of smell are located within the nasal cavity, accessed through the nostrils. Therefore, the function of the nostrils is directly linked to our ability to perceive odors.
