Eyes and ears are the sense organs of human beings.

The proverb “Closed eyes open up ears” tells about the importance of our ears when eyes are closed.

Ear is a sense organ of hearing. Human beings have two ears. Ears help us to hear different sounds and discriminate against them. It is an important organ for humans. We should also protect our ears from pointed objects, loud sounds, etc.

Explanation:

Human beings have five sense organs- Eyes, Ears, Nose, Skin and Tongue.

An eye is the organ of vision. Through eyes we can see the world, differentiate our surroundings depending on its shape, size, color, length, breadth, height, distance, etc.

Because of eyes we gain knowledge about our surroundings. Eyes are important to us and we should protect our eyes.  

An ear is the organ of hearing. We can hear different sounds and differentiate them because of our ears. We should also protect our ears from hearing loss.

When we close our eyes, we cannot see anything, but we can hear different sounds because of our ears. Ears receive sound through the pinna (outer part of ear) and direct them into ear`. The sounds pass through the inner part of ears and reach the brain that recognizes sound. Ears are important for hearing.
