Why do ears help us?
They help us with hearing, and balance. They serve as great
tools for one of the humans amazing 5 senses...... with hearing
they help as filttering cups, you could say. Your ears... the
pinna(outer part) funnels sound into the external auditory canal, a
short tube that ends at the eardrum(tympanic membrane) where the
sound comes together and you then hear it. Have you ever cupped
your hand behind your ear? notice how everything is louder and you
can hear much more?! Think of your ears as your hand, and what your
hand was doing for your ears is what your ear does for you......
with balance that's what your equilibrium in your inner ear is
for....The fluid-filled semicircular canals (labyrinth) attach to
the spiral-shaped cochlea and nerves in the inner ear. They send
information on balance and head position to the brain. The
eustachian (auditory) tube drains fluid from the middle ear into
the throat (pharynx) behind the nose.
