What substance lines your throat and help the food slide down?

The substance that lines your throat and helps food slide down is called mucus.

Mucus is a sticky, slippery substance produced by your body's mucous membranes. It serves many important functions, including:

* Lubrication: Mucus in your throat helps food slide down easily, preventing irritation and making swallowing smoother.

* Protection: Mucus traps dust, bacteria, and other foreign particles, protecting your body from infection.

* Moisture: Mucus keeps your throat moist, preventing dryness and discomfort.

While mucus might not be the most glamorous substance, it plays a vital role in keeping your throat healthy and functional!
