Ans: Ear Wax

The ear canal is lined with hair follicles and glands that produce a waxy oil called cerumen. The wax will most often make its way to the opening of the ear. There it will fall out or be removed by washing.

Wax can build up and block the ear canal. Wax blockage is one of the most common causes of hearing loss.

Ear wax protects the ear by:

• Trapping and preventing dust, bacteria, and other germs and small objects from entering and damaging the ear
• Protecting the delicate skin of the ear canal from getting irritated when water is in the canal

Taste is the sensation produced when a substance in the mouth reacts chemically with taste receptor cells located on taste buds. Taste, along with smell and trigeminal nerve stimulation, determines flavors of food or other substances.

The sensation of taste can be categorized into five basic tastes: sweetness, sourness, saltiness, bitterness, and umami.

The basic tastes contribute only partially to the sensation and flavor of food in the mouth—other factors include smell,detected by the olfactory epithelium of the nose;texture,detected through a variety of mechanoreceptors, muscle nerves, etc. temperature, detected by thermoreceptors; and "coolness"and "hotness".

As taste senses both harmful and beneficial things, all basic tastes are classified as either aversive or appetitive, depending upon the effect the things they sense have on our bodies.Sweetness helps to identify energy-rich foods, while bitterness serves as a warning sign of poisons.
