orrnyílásokkal

Orrnyílásokkal refers to the nostrils of the nose. These are the two openings that allow air to enter and exit the nasal cavity. Each nostril is lined with hairs, also known as vibrissae, which help to filter out larger particles from the inhaled air. Beneath the hairs, the nasal lining is covered in mucus-producing cells and cilia, which trap smaller particles like dust and pollen and move them towards the throat to be swallowed or expelled.

The structure of the nostrils plays a crucial role in respiration. They warm and humidify incoming air before it reaches the lungs, protecting the delicate lung tissues from cold, dry air. The sense of smell, olfaction, is also primarily initiated by the nostrils, as odor molecules are detected by olfactory receptors located within the nasal cavity, just behind the nostrils. The size and shape of the nostrils can vary among individuals and are a characteristic feature of facial anatomy. In some cases, medical conditions or trauma can affect the patency or appearance of the nostrils.
