c.	The eustachian tube allows passage of air between the middle and outer ear.
d.	It helps equalize air pressure on both sides of the tympanic membrane.

 

 

ANS:  D

The eustachian tube allows an equalization of air pressure on each side of the tympanic membrane so that the membrane does not rupture during, for example, altitude changes in an airplane. The tube is normally closed, but it opens with swallowing or yawning.
