GENERAL HISTOLOGY

Detailed explanation-1: -Where Does Air Go? Air enters the respiratory system through the nose or the mouth, then travels down a pathway to the lungs. In the nostrils, air gets warmed and moistened.

Detailed explanation-2: -Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.

Detailed explanation-3: -The Paranasal Sinuses Surround the Nasal Cavities Mucosae line the paranasal sinuses and help to warm and humidify the air we inhale.

Detailed explanation-4: -The nasal cavity lies above the bone that forms the roof of the mouth and curves down at the back to join the throat. It is divided into two sections called nasal passages. Air moves through these passages during breathing. The nasal passages filter and warm the air, and make it moist before it goes into the lungs.

Detailed explanation-5: -Drink more water. Take care that your beverages don’t have too much sugar. Boost the humidity. In the winter months, try a bedroom humidifier. Enjoy a warm bath. The moist air will help for a while. Try a nasal spray. Apply a moisturizer.
