The eustachian tubes branch off the pharynx. These allow pressure balance to be maintained behind the eardrums.
Bronchi are the two tubes that branch off into each lung.
Nasopharynx
Pharynx and inner ear
The pharynx, the larynx and the trachea (windpipe), in that order, connect the mouth to the bronchial tubes.
The throat or pharynx has an esophagas and a trachea.
The eustation tubes
The "Trachea".
These are the bronchi. (One bronchus, two bronchi).
The auditory tubes, also known as the Eustachian tubes, open into the nasopharynx region of the pharynx. This connection helps equalize pressure between the middle ear and the atmosphere, which is important for maintaining proper hearing function.
Bronchioles
Bronchioles
The two main tubes through which air flows when you breathe are the trachea, also known as the windpipe, and the bronchial tubes, which branch off from the trachea and lead to the lungs.
