Question

Mucus trapping bacteria is the blank and blank systems working together.

Answer 1

Answer:

immune and respiratory

Explanation:

• Mucus is a transparent, watery secretion produced by the respiratory system particularly, the mouth, sinuses, throat, lungs and intestines.
• Mucin, a major component of mucus, can act as protective substances and lubricants.
• Mucus produced in the nose and sinuses helps trap pathogenic bacteria in the lining of the respiratory tract.
• This trapping of pathogens is part of the innate immune system and the body's first line of defense against pathogens.
• Mucins have also been known to help break down bacterial biofilms i.e (a thick layer of bacteria).
