Cilia do not surround your mouth. You are probably talking about the mustache and beard.
cilia that surrounds the paramecium serves as their mode of movementn.
Cilia
The cilia is supposed to keep the dust particles away from the alveoli. The dust from the air that is inhaled from the mouth is filtered by the cilia in the pharynx.
To filter out particles that are possibly harmful if allowed to reach your lungs.
cilia in vorticella is usually concetrated around the mouth end of the organism. when vorticella is motile, temporarily, cilia will form around its body and when it is anchord it disappears. cila creates water current to direct food towards its mouth
Orbicularis Oculi
what is the arm like structures surrounding the mouth of cnidarians
Cilia and flagella have a single membrane that surrounds their structure. They are composed of a core of microtubules arranged in a "9+2" pattern, which is encased by this membrane. This design allows them to function effectively in cellular movement and signaling.
To move, and to atract other organisms into their mouth groove.
Ciliophora can be classified under Protista or Protozoa. They have many cilia lying in rows on the body and used for movement, sometimes with more cilia around the mouth and used for feeding.
The goblet cells in the respiratory epithelium produce mucus, while ciliated cells have cilia that help waft the mucus towards the mouth and nose, aiding in the clearance of debris and pathogens from the airways.
The cilia in the trachea is same as the cilia in the nose. They both clean the air before entering our lungs. If there's no cilia, then the lungs would most likely have problems, if not dealt with quickly. Noticed how when you breathe through your mouth more often you cough more. This is because of the cilia cleaning the air and also forcing the dirty particles out of the respiratory system.
