What is the process of expelling sputum from the chest?
Expectpration - "coughing up of mucus or sputum from the throat and respiratory tract"
What is the mucus?
Also referred to as the mucociliary escalator; covers bronchi, bronchioles, and nose in the respiratory tract. It is composed of the mucus-secreting goblet cells and ciliated epithelium found in the mucosa lining of the respiratory tract. The cilia are continually beating, pushing mucus up and out into the throat, forming a major barrier against infection. Microorganisms trying to infect the respiratory tract are caught in the sticky mucus and moved up by this mucuciliary escalator. The mucus is pushed into the throat and swallowed, then digested by the body, preventing the microorganisms from causing any harm/infection to the body

How is mucus moved up the respiratory tract?
Mucus, with dirt and pathogens trapped to it, is wafted up the respiratory tract by cilia, which also line our nasal and tracheal passages. This process is comparable to a conveyor belt motion.
What is difference between phlegm and sputum?
Phlegm is the thick mucus and sputum the material coughed up from the lining of the respiratory tract.
What is catarrhal?
a surface inflammation associated with greatly increased secretion of clear mucus.

Function of cilia in air passage?
Mucus is produced by the goblet cells, in the airways dust particles etc will stick to the mucus, cilia cells then use energy to sweep the mucus up back up through the trachea, where we can swallow it and dust particles and pathogens etc can be broken down by enzymes in the stomach, or we can expell it by sneezing or coughing.
How is the structure of a ciliated columnar epithelium cell related to its function?
The cilia in the respiratory tract comprise the mucociliary escalator. Also covering the respiratory tract is a layer of mucus, which serves to trap foreign particles like bacteria and viruses. Once stuck to the mucus, the cilia sweep in an upward direction. The mucus moves up to the pharynx where it is either coughed out or swallowed. This process is called mucociliary clearance.
Role of cilia in respiratory tract?
The cilia are very important in the respiratory tract. Cilia are projections off cells called pseudostratified columnar cells. They are constantly moving back and forth, like blades of grass in the wind. Cilia act in conjunction as one big broom, sweeping particles trapped in the mucous up to the throat to be expelled like this *OBNOXIOUS SMOKER'S COUGH.*
Is Sputum a fluid normally found in the lower respiratory tract and is not associated with pathology?
I think your thinking of applesauce. Sputum is actually found in llama spit.
How are dust particles that enter the respiratory system in the air expelled?
It gets caught in the mucus of the respiratory tract, and then the small cilia moves them up towards the mouth. Then you either cough it out or swallow it, so it goes into your stomach instead of your lungs. xoxo , Simone♥
