Question

Answer

The function of cilia in the trachea and bronchi is to protect the airways from being damaged or infected by particles of dust or foreign matter.

Explanation:

Air that is inhaled may not necessarily be free of dust particles. For this reason, there must be something to remove the potentially harmful matter from the body. The cilia in the trachea and bronchi act as a defence system for the body by keeping the airways clear of mucus, dust, dirt, and other foreign matter. This allows us to breathe easily without disruption. For example, in Beijing, the air is so full of dust that many people must wear masks to protect themselves from breathing in the harmful particles.

Answer

The lining of your airway containsmucus, which serves to moisten the air you breathe. ... The sweeping motion of cilia moves the mucus and whatever is trapped in it up toward your throat and nasal cavity. Cilia not only sweepmucus up and out, they act as filters that trap particles in the air you inhale.

Answer

Function of Tracheal Cilia:
Tracheal cilia play a crucial role in the respiratory system by aiding in the removal of mucus and foreign particles from the airways. Here is an explanation of the function of tracheal cilia in detail:

Passing mucus out:
- The main function of tracheal cilia is to move mucus, which contains trapped dust, bacteria, and other particles, out of the respiratory tract.
- The cilia constantly beat in a coordinated manner, creating a wave-like motion that propels the mucus upwards towards the throat.
- Once the mucus reaches the throat, it can be either swallowed or expelled from the body through coughing.

Importance of removing mucus:
- Removing mucus from the respiratory tract is essential for maintaining healthy lungs and preventing infections.
- If mucus is not effectively cleared from the airways, it can lead to congestion, inflammation, and increased susceptibility to respiratory infections.

Role in respiratory health:
- The coordinated movement of tracheal cilia helps to keep the airways clear and allows for efficient exchange of oxygen and carbon dioxide in the lungs.
- This process is crucial for maintaining proper lung function and overall respiratory health.
In conclusion, the function of tracheal cilia is to pass mucus out of the respiratory tract, helping to keep the airways clear and free from harmful particles. This process is essential for maintaining healthy lungs and preventing respiratory infections.
