Our ears help us hear sounds because they contain structures like the eardrum and cochlea that process sound waves.

• The eardrum vibrates when sound waves hit it.
• These vibrations are transferred to the cochlea, a spiral-shaped organ.
• The cochlea converts these vibrations into electrical signals.
• These signals are sent to the brain, allowing us to perceive sounds.

We utilise our tongue to experience the flavour of food. This organ plays a crucial role in tasting, as it is covered with taste buds that detect different flavours.
