Ciliated cells in the airway help to move mucus and foreign particles out of the respiratory tract by beating their cilia in a coordinated manner. This action helps to keep the airways clear and protect the lungs from potential infections and irritants.
Mucus and cilia keep the lungs free from bacteria and dust particles by trapping dust so that it can be swallowed and broken down by the digestive system. Alternatively, dust and bacteria can be expelled when sneezing or coughing.

Tilt the head back or jut the jaw to keep somebody's airway open to help them breathe.

Cilia are tiny hair-like structures that line the respiratory tract and help sweep mucus, dirt, and pathogens out of the lungs. Mucus traps particles and microbes, preventing them from reaching the lungs. Together, cilia and mucus form the mucociliary escalator, which helps to keep the airways clear and clean in a healthy non-smoker.
Mucus (aka snot) helps to keep mucus membranes lubricated/hydrated and helps clear antigens (virus, bacteria, allergens, etc) from the body.
This is because frogs secrete a mucus which help keep their skin moist
At 5-months, a nose bulb is still good to use to suck the mucus out of a baby's nose. It is important to keep your baby hydrated, whenever they are ill. So suck out the mucus and maintain a normal feeding schedule.
The mucus produced by goblet cells in the trachea helps to trap dust, debris, and pathogens, preventing them from entering the lungs. It also helps to moisturize and protect the lining of the trachea from irritants and infection.
The conjunctiva is a clear, thin membrane that covers the white part of the eye and lines the inside of the eyelids. Its main function is to protect the eye by producing mucus and tears, which help to lubricate the eye and keep it moist.
Mint leaves, lemon juice, and papaya can help keep skin clear.
