A correct answer

Answer 2

Mucus

Step-by-step explanation:

Harmful microbes that could pass by the nose into the lungs and cause infections are taped earlier and excreted by mucus.

Mucus traps invading pathogens preventing them from reaching sensitive parts of the body thereby preventing diseases.
