Air enters our body through the nose. The air passes through the nasal passages. On both sides of the nose are structures called turbinates which humidify and warms the air. The nose is divided into 2 halves by the septum. On the septum there is an area called the Little’s Area which is prone to bleeding. This is often seen in children.
The air proceeds down the back end of the nose called the postnasal space. The adenoids are situated in this location. From there it enters the back of the mouth known as the oro-pharynx. The tonsils sit on two sides of the oropharynx.
Further down the throat the air passes between the vocal cords in the larynx and enters the the windpipe also called the trachea into the lungs.
