I have any idea for these.
funk you all they no answer !@#$%^&
1) Microscopic hairs of the windpipe are always moving or vibrating.
To understand why microscopic hairs in the windpipe are always moving, we need to explore the concept of cilia. Cilia are tiny hair-like structures found on the surfaces of many cells in the human body, including the cells lining the windpipe (also known as the trachea). The purpose of these cilia is to move mucus and trapped particles out of the respiratory system.
The movement of cilia is essential for respiratory health. They beat rhythmically and create coordinated waves, which help propel mucus and trapped particles upwards towards the throat. This constant movement of the microscopic hairs ensures that foreign particles, such as dust, allergens, or bacteria, do not remain stuck in the windpipe. Instead, they are pushed towards the throat, where they can be swallowed or expelled through coughing or sneezing.
2) The cilia of the windpipe move harmful substances upward, away from the lungs.
Now that we understand the purpose of cilia in the windpipe, it becomes clear how they aid in removing harmful substances. When harmful substances, such as dust, smoke, pollen, or bacteria, enter the respiratory system, the cilia help move them upward, out of the lungs.
As mentioned earlier, the coordinated beating of cilia creates waves that sweep these substances towards the throat. From there, they can be swallowed and sent into the digestive system, where they are disposed of safely. By moving harmful substances away from the lungs, the cilia help protect the delicate respiratory tissues and prevent potential damage or infections.
3) You build a heavy gust of air when you cough or sneeze.
When you cough or sneeze, the action generates a forceful release of air from your lungs. This forceful expulsion of air creates what can be described as a "heavy gust" of air. The air is expelled rapidly and forcefully, often accompanied by a distinct sound.
Coughing and sneezing serve important purposes in the respiratory system. They are natural defense mechanisms designed to protect the lungs and airways from irritants, clear mucus or foreign particles, and prevent potential infections. By generating a heavy gust of air, coughing and sneezing help dislodge and propel harmful substances out of the respiratory system.
4) Coughing and sneezing help push harmful substances from the respiratory system.
When you cough or sneeze, the forceful exhalation of air from the lungs not only creates a heavy gust but also helps push harmful substances out of the respiratory system.
Coughing is triggered when the respiratory system senses an irritant, such as excessive mucus, foreign particles, or an infection. The forceful expulsion of air from the lungs during a cough helps dislodge and propel these substances out of the respiratory tract. Similarly, sneezing is a reflexive response to irritation in the nasal passages. When you sneeze, air is forcefully expelled through the nose, helping to clear irritants from the nasal cavity and upper respiratory system.
In summary, coughing and sneezing act as protective mechanisms that aid in removing harmful substances from the respiratory system. Their forceful expulsion of air helps push these substances out of the airways and prevent potential damage or infections.
