Lung structures include:
The nose, pharynx, trachea, and bronchi.
The eustachian tube is a small tube that runs from the pharynx to the ear and deals with equalizing pressure on the ear drum. The pharynx actually has three different parts: the oropharynx, the nasopharynx, and the laryngopharynx. Technically, all three parts are used in the respiratory system, though they are not physically connected to the lungs. The bronchi, however, are connected to the lungs. They connect the trachea to the two lungs.
alveoli
Yes. The eustachian canal connects to the nasopharynx.
Nasopharynx
Eustachian tubes lead to the eardrum. The name for the throat of the from is the gullet.
Pharynx
the eustachian tube connects the pharynx to the middle ear
Pharynx and inner ear
The digestive and respiratory systems share the mouth and the pharynx. The respiratory system also includes the glottis, trachea, bronchi, bronchioles and alveoli.Buccal cavity? Pharynx?pharynxThe Larynx
the trachea (windpipe)
The eustachian tube connects the throat to the inner ear and equalises the inner and outer ear pressure. It is this which causes the pop! when you fly in an aircraft and you swallow. The pop is the eustachian tube clearing.
