This part of your ear allows the ‘popping’ that happens when you fly,
While this part of your ear makes you feel dizzy when you get off the t-cup ride at an amusement.
Eustachian tube. This tube connects the middle ear to the back of your nose and it allows for drainage of fluid and for pressure to be released. It is small however and can become narrowed or blocked by the swelling of soft tissues locally. The resulting buildup in pressure, either in an aircraft or if infection is present, can be extremely painful. Popping in your ears is when the pressure inside the middle ear is balanced with the pressure outside it, which often gives great relief and improves hearing. This is different from when water is trapped in the outer ear after swimming, although the effect can be similar.
Fluid moving in the semicircular canals causes you to feel dizzy after you stop spinning.
