Question

a slimmy substance present in nasal cavity​

Answer 1

What is nasal discharge? Mucus isn't just a slimy material in your nose — it actually has a useful purpose. It traps bacteria, other germs, and debris, and prevents them from entering your lungs. In some cases, such as when you have a cold or allergies, mucus may flow out of your nose or down your throat.

I hope this will help you...xD✌
