Nasal glands are specialized structures located in the lining of the nasal cavity. They produce mucus, which helps to moisten the air we breathe and trap dust, allergens, and pathogens. This mucus plays a crucial role in protecting the respiratory system by preventing harmful particles from entering the lungs. In addition to mucus, nasal glands also secrete antimicrobial substances that help fight infections. These glands are part of the body's defense mechanism, ensuring that the air reaching the lungs is clean and humidified. Proper functioning of nasal glands is essential for maintaining respiratory health and overall well-being.
