Why is it false that dust particles trapped in the mucus are swept away by tiny hair like alveoli?
It's false that dust particles are swept away by tiny hair-like alveoli because alveoli are the small air sacs in the lungs where gas exchange occurs, not structures designed for trapping dust. Instead, dust particles are trapped in mucus within the airways, and the cilia—tiny hair-like structures lining the respiratory tract—move the mucus upward toward the throat to be expelled or swallowed. Alveoli lack cilia and do not participate in this cleansing process.

Where are dust particles trapped in mucus and hairre?
Dust particles are trapped in mucus in the respiratory tract, such as the nose and throat, and in hair on our skin. Mucus acts as a sticky barrier that captures dust particles as we breathe, while hair on our skin can also trap dust before it reaches our respiratory system.
What are cells that reach the surface either secrete mucus or bear cilia that sweep away mucus and trapped foreing particles?
The function of cilia is to remove foreign particles and mucus from the surface of the respiratory system. This is to prevent the blockage of airways.
How do cells lining the bronchus protect the alveoli?
At the top of the respiratory system, the nostrils (also called nares) act as the air intake, bringing air into the nose, where it's warmed and humidified. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air. :D hope it helps
What is mechanism of feeding on amphioxus larva?
Amphioxus has a wheel organ which creates a current. This current carries water into the mouth, where food is trapped in the pharynx by cilia and mucus. Excess water is filtered through the pharyngeal slits to the atrium and out the atriopore.
What is the long cilia protude from the nasal epithelium and are bathed with mucus?
The long cilia protruding from the nasal epithelium are called respiratory cilia. They help to move mucus and trapped particles out of the respiratory tract, aiding in the clearance of foreign substances and maintaining respiratory health.
What gets trapped in the mucus elevator?
Infectious agents, small aerosol and dust particles are trapped in the mucus elevator to prevent their invasion in lungs.

The body region where a ciliary escalator helps to sweep microbes trapped in mucus away from that body site is the urinary tract?
Actually, the body region where a ciliary escalator helps to sweep microbes trapped in mucus away is the respiratory tract, specifically in the lungs. The cilia lining the respiratory tract beat in a coordinated manner to move mucus and trapped microbes up and out of the airways.
What is the difference between mucus and cilia?
Mucus is a slimy substance produced by goblet cells, which helps trap and remove foreign particles, while cilia are tiny hair-like structures that move in a coordinated manner to sweep away mucus and trapped particles from the airways. Together, mucus and cilia form the mucociliary escalator, a defense mechanism in the respiratory system to protect against infections.
How does Exposure to tobacco smoke immobilizes cilia how might this effect explain smokers have increased incidence of coughing?
The mucus linings of your bronchi (airways) are responsible for trapping some of the larger foreign particles that you breathe in all day every day. Cilia are responsible for moving that mucus upward and out of your airways to aid in expectoration (coughing up phlegm). If the cilia are destroyed, the foreign particles are trapped in your mucus linings and the mucus cannot be pushed out of your lungs and into you esophagus like usual. This can cause respiratory infections and increased coughing. Not to mention cigarette smoke destroys your type II pneumocytes in your alveoli, which causes pulmonary disorders like emphysema.
What structures trap foreign particles and bacteria in the nose and trachea?
Mucus in the nose and trachea traps foreign particles and bacteria. The cilia, tiny hair-like structures in the respiratory tract, move the mucus and trapped particles upwards to be swallowed or expelled. This process helps to protect the lungs and respiratory system from harmful invaders.
Why does the lining of the trachea contain mucus-secreting cells and cells with cilia?
some cells in this lining secrete a sticky liquid called mucus, which traps particles of dirt or bacteria that are breathed in. Other cells are covered with timy hair-like structures called cilia. It sweeps the mucus and trapped particles out toward the mouth.
Why do you have cilia in your esophagus?
because it has to trap all dust particles that didn't get trapped when going through nose and mouth...... by epidemic skate shop

What is the function of cilia in the nostrils?
Cilia in the nostrils help to trap and filter out particles like dust, pollen, and bacteria from entering the respiratory system. They also help to sweep mucus and trapped particles towards the throat where they can be expelled or swallowed.
