nasal physiology

Nasal physiology refers to how the nose works to filter, warm, and humidify the air we breathe. The nose contains structures called turbinates that increase surface area, allowing air to interact with blood vessels that warm and moisten it. Mucus traps dust, allergens, and pathogens, helping to protect the lungs. Olfactory receptors in the nasal cavity are responsible for our sense of smell. Overall, these functions ensure that air entering the lungs is clean, warm, and well-hydrated, which is crucial for respiratory health.
