Question

how does our nose stop diseases from getting inside of our body

Answer 1

Explanation:

Nasal breathing increases nitric oxide production in the sinuses which keeps blood pressure levels healthy. Nitric oxide is also antifungal, antiviral, antiparasitic, and antibacterial. It helps the immune system to fight infections. Nasal breathing improves sleep along with better memory, focus and concentration.

Answer 2

Answer:

The hair and mucus inside our nasal passage traps dust, waste, pollen particles and larger microbes, thus preventing their entry into our body, but is not very effective against most microbes.
