Why is it harmful to respire through mouth than through nasal openings ?

Expert Answer:

The air passing through nostrils is filtered by fine hairs that line the passage. The passage is also lined with mucus which helps in this process. No such filtration occurs when air passes through mouth. So the foreign particles gain easy entry in to the body, when respiring through mouth.
