A label diagram of the ear. showing the parts of the ear including the Eustachian tube

The function of the Eustachian tube within the ear is to drain the middle ear , let air pass through to clear it and also to protect it. The tube connects itself from the middle ear to the pharynx. If this does not occur the ear can lead to middle ear inflammation( infection in the middle ear more common to children because they have shorter Eustachian tube which offers weak protection) The older humans get the longer the tube grows , when we are younger the tube is short.

The picture above shows one of the funcation of the Eustachian tube.
