orrnyílásoktól

orrnyílásoktól refers to the nasal passages or nostrils. These are the two external openings of the nose, serving as the primary entry point for air into the respiratory system. Each orrnyílás is lined with a mucous membrane that helps to warm, humidify, and filter inhaled air, trapping dust, pollen, and other particles. Hairs within the nostrils also contribute to this filtration process. The orrnyílások play a crucial role in the sense of smell, as olfactory receptors are located in the nasal cavity, just beyond the nostrils. They are also important for breathing, allowing for both inhalation and exhalation. The shape and size of the orrnyílások can vary significantly between individuals. Conditions affecting the orrnyílások can impact breathing and smell, such as nasal congestion due to allergies or infections.
