nässtrukturer

Nässtrukturer refers to the intricate anatomical formations within the nasal cavity. These structures are crucial for the complex functions of the nose, including respiration, olfaction, and filtering inhaled air. The most prominent features are the turbinates, also known as conchae, which are bony projections covered by highly vascularized mucous membranes. These turbinates, typically three in number (superior, middle, and inferior), greatly increase the surface area of the nasal cavity. This expanded surface area allows for more efficient warming, humidifying, and filtering of the air before it reaches the lungs. Tiny hairs, or cilia, lining the nasal passages also play a role in trapping larger particles like dust and pollen.

Beneath the mucous membrane, a rich network of blood vessels helps to warm the incoming air. The mucous itself traps smaller particles and pathogens, which are then moved towards the pharynx by the coordinated beating of the cilia, where they can be swallowed and destroyed by stomach acid. The olfactory epithelium, located in the upper part of the nasal cavity, contains specialized sensory cells responsible for detecting smells. The arrangement and function of these nässtrukturer are vital for maintaining respiratory health and our sense of smell.
