Balance Everyone Knows That Your Ears Are Responsible for Your Sense

Balance
Everyone knows that your ears are responsible for your sense of hearing. But did you also know that your ears are also partially responsible for your sense of balance? Your inner ear contains something called the vestibular system, which is a key component in your body's ability to establish and maintain balance.
The vestibular system mainly consists of three semicircular canals. Each semicircular canal has a different orientation, allowing them to detect a variety of movements. The canals are filled with a fluid called endolymph. When you move your head, the fluid in the canals also moves; this movement sends signals to the brain about the position of your head. Your brain uses this information to help your body stay balanced.
Damage to the vestibular system caused by disease or injury can severely affect a person's balance. Consuming too much alcohol can also temporarily affect the vestibular system. Because alcohol thins the blood, it also changes the viscosity of the endolymph. The thinned-out endolymph sends signals to your brain that your body is rotating even though it is not. This is why many people feel like the room is spinning when they are drunk.
What is the best summary for the passage?

A) The viscosity of the endolymph is perhaps the most important part of maintaining balance in the body.
B) Consuming too much alcohol will severely impact the way our body establishes and maintains balance.
C) The vestibular system contains intricate canals and fluid and plays an important role in maintaining our balance.
D) Overall, the brain plays an important role in establishing balance.
