Actin and myoglobulin are the compositions building muscles' stretching function. Microtubulin is the basic substance which provides the flagellum and cilium the function of movement.
The delicate hair-like cilia in the airways and lungs start recovering within weeks, and are restored after 9 months, improving resistance to infection.
The delicate, hair-like structures inside the lungs known as cilia, which help to fight infections, will have recovered from the toll of cigarette smoke.
Smoking damages the cilia, making them less able to clear even the normal amount of mucus and secretions, let alone the increased volume associated with pneumonia.
The mucociliary escalator consists of mucus that traps invaders and tiny hairs called cilia that carry the mucus toward the mouth, where it can be coughed out.
