Final answer:

The vestibular system in the inner ear enables us to perceive 'up' and 'down' with closed eyes.


Explanation:

The ability to distinguish 'up' from 'down' even with closed eyes is attributed to the vestibular system. This system, located in the inner ear, consists of the utricule and saccule, semicircular canals, and vestibular sacs that work together to sense head orientation and movement, helping maintain balance and direction.
