    Study Notes

    Nasal Cavity: Turbinates

    • Turbinates, also known as conchae, are bone and cartilage folds in the nasal cavity that create turbulence in the airflow.
    • The primary function of turbinates is to warm the air through a heat exchange with the surrounding tissues.
    • Turbinates also humidify the air by producing mucus and other fluids in the nasal cavity.
    • Additionally, they filter the air by removing foreign particles, which are trapped in the mucus.
