Nasal breathing refers to the state of inhaling and exhaling through the nose.
It is considered superior to mouth breathing for several reasons. Breathing through the nose has numerous health benefits due to the fact that the air travels to and from the external environment and the lungs through the sinuses as opposed to the mouth. The sinuses do a better job of filtering the air as it enters the lungs. In addition, the smaller diameter of the sinuses create pressure in the lungs during exhalation, allowing the lungs to have more time to extract oxygen from them. When there is proper oxygen-carbon dioxide exchange, the blood will maintain a balanced pH. If carbon dioxide is lost too quickly, as in mouth breathing, oxygen absorption is decreased. Nasal breathing is especially important in certain situations such as dehydration, cold weather, laryngitis, and when the throat is sore or dry because it does not dry the throat as much.
Nasal breathing in public is considered to be more socially acceptable and attractive than mouth breathing.
The air moves up your nose through your trachea which is lined with cartilagenous rings, this then splits into 2 bronchi (singular bronchus) and then these branch into bronchioles which in turn branch off and end in alveoli
