cilia
The cilia are always moving, bacteria or particles of dust trapped in the mucus are moved away by cilia. The cilia waft the mucus containing bacteria and dust up to the back of the throat, so that it doesn't block up the trachea and thus keeps it clean.
Mucus is a sticky substance. Describe how mucus and cilia keep the lungs free of bacteria and dust particles.
Mucus naturally occurs. As it is sticky, it is there to trap airborne particles before they get to the lungs. To expel mucus, for example, by coughing, is quite normal.
Ciliated epithelium is found as the lining the respiratory tract from the nose to the trachea. This cilia secretes and propels mucous as well as sweeping dust and other irritants away from the lung.
mucus is moved by the cell epithelial cell
The ciliated cells has tiny hairs on it, called cilia, which sweep mucus, which is produced by goblet cells, up the airway. The mucus traps dirt particles and stop them from entering the lungs and causing infection. The ciliated cell therefore sweeps mucus up the airway where it is either swallowed or coughed out.
goblet cell secret lubricatig fluid which lubricate the wall of small intestine and these seretion resist the damaging of small intestine from rigid foog which are undigested by stomah,and it helps easly propale throghout the small intestine by paristilisis
Smoker's cough results from damage of the cells that line the trachea which have cilia. The cilia are damaged so that the mucus cannot be moved and therefore be swallowed. Coughing helps to remove the mucus. Also smoke irritates the cells of the trachea and produce the cough
You can find them in the trachea which is another name for the windpipe! Hope this helps! You can find them in the trachea which is another name for the windpipe! Hope this helps!
The process that moves materials into cells is called endocytosis. During endocytosis, the cell membrane surrounds particles or substances outside the cell, forming a vesicle. The vesicle then fuses with the cell membrane and releases its contents into the cell.
Through integral proteins (tube shaped proteins that have one opening in the extra cellular matrix and the other opening inside the cell).
Small particles move faster across the membrane.
