Taste

Taste is the sensation produced when a substance in the mouth reacts chemically with taste receptor cells located on taste buds, which are mainly on the tongue.

The human tongue has between 2000 and 5000 taste buds that are located on the back and front, which replace themselves every 10 days. Others are located on the roof, sides and back of the mouth, and in the throat. 

Your lungs have taste buds that can detect bitterness.

You have exactly the same taste buds in your intestine as you do in your tongue. In your tongue, the buds are hooked up to your brain's pleasure centers. In your intestine, they're hooked up to your pancreas where they trigger the release of insulin.

The tongue is covered with thousands of small bumps called papillae, which are visible to the naked eye. Within each papilla are hundreds of taste buds. Each taste bud contains 50 to 100 taste receptor cells.
