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
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.
What did Boyle observe in his experiment with gas trapped in a J-tube?
Boyle's experiment with gas trapped in a J-tube showed that when the volume of a gas is decreased, the pressure increases proportionally. This allowed Boyle to establish Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at a constant temperature.
What two things are trapped and swallowed by cilia cells at the back of the throat?
The two things that are trapped and swallowed at the back of the throat by cilia cells are saliva and food. Medicines in the form of pills can also be trapped and swallowed, but trapped pills might make the person choke instead of swallow.
What titan is trapped in a volcano?
In Greek mythology, the titan Prometheus is often associated with being chained and trapped on a mountain rather than in a volcano. However, there is no specific titan commonly associated with being trapped in a volcano.
Bronchial spasm resulting in decreasing air movement and air trapped in alveoli?
asthma
What is the bronchial spasm resulting in decreased air movement and air trapped in alveoli?
This condition is known as bronchospasm, which is characterized by the constriction of the muscles surrounding the airways in the lungs. This can lead to difficulty breathing, decreased airflow, and air getting trapped in the alveoli, causing symptoms such as wheezing and shortness of breath. Bronchospasm can be triggered by various factors like asthma, allergies, or respiratory infections.

How does silicosis start?
What is known is that particles of silica dust get trapped in the tiny sacs (alveoli) in the lungs where air exchange takes place. White blood cells called macrophages in the alveoli ingest the silica and die.

What percent percentage of fresh air is inspired with each breath in normal individuals at rest does not reach the alveoli?
About 30%. The air trapped in ANATOMICAL DEAD SPACE which is about 150 ml does not reach into the alveoli in each breath of 500ml (TIDAL VOLUME)approx.
What is a bronchial obstruction?
The bronchi are the two branches of the windpipe that lead into the lungs. If they are blocked by tissue swelling, cancerous tumors, or foreign objects, a lung abscess may form from infection trapped behind the blockage.
What does insulation materials contain trapped?
Insulation materials contain trapped air or another gas that reduces heat transfer by convection and conduction. The trapped air acts as a barrier that slows down the movement of heat through the material, helping to maintain a consistent temperature.
Why is a symptom of emphysema breathlessness?
emphysema may result from the progression of chronic bronchitis or other conditions as air becomes trapped within alveoli and causes them to enlarge. as the alveoli enlarge, their walls rupture and then fuse into large irregular spaces-these ruptures reduce the total surface area of the lung, making breathing difficult.
What did Boyle observe in his experiment with gas trapped in a J-tube?
Boyle's experiment with gas trapped in a J-tube showed that when the volume of a gas is decreased, the pressure increases proportionally. This allowed Boyle to establish Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at a constant temperature.
Emphysema from smoking and exposure to heavy pollution causes alveolar to expand and rupture Describe how this would compromise respiratory function?
Emphysema leads to the destruction of alveoli, resulting in larger, less efficient air sacs that reduce the surface area available for gas exchange. This impairment hinders oxygen uptake and carbon dioxide removal, leading to decreased lung function and breathlessness. Additionally, the loss of elastic recoil makes it difficult to expel air, causing trapped air in the lungs and further compromising respiratory efficiency. Ultimately, these changes can result in significant respiratory distress and decreased overall oxygenation of the body.
Why does smog get trapped in our troposphere?
Smog gets trapped in our troposphere due to a combination of factors such as temperature inversions, lack of wind or air movement, and the presence of pollutants like sulfur dioxide and nitrogen oxides. These factors can lead to the accumulation of pollutants close to the Earth's surface, causing smog to be trapped and linger in the lower atmosphere.
