Detailed explanation-1: -Breathing through the nose is more beneficial than breathing through the mouth. Nose breathing filters, heats, and humidifies air as it enters the body. This may reduce the risk of infections and other problems.
Detailed explanation-2: -Nose breathing is beneficial primarily because it allows your nasal cavities to: reduce exposure to foreign substances. humidify and warm inhaled air. increase air flow to arteries, veins, and nerves.
Detailed explanation-3: -The small hairs present in the cavity helps to filter the particles of dust and other foreign matter. The air in the nasal cavity gets warmed (because nasal cavity has very good blood supply) and moistened before it enters to the lungs.
Detailed explanation-4: -Turbinates (conchae): There are three pairs of turbinates located along the sides of both nasal cavities. These folds inside your nose help warm and moisten air after you breathe it in and help with nasal drainage.
Detailed explanation-5: -Air enters the body through your mouth and nose. The air is warmed, moistened and filtered by mucous secretions and hairs in the nose.
