Question

Which of the following is not conducting part in respiratory system-a)bronchi b)terminal bronchiole c)alveoli   d)secondary bronchioleCorrect answer is option 'C'. Can you explain this answer?

Answer

Alveoli is that part of respiratory system where,  diffusion of gases occur...

Answer

Alveoli is not conducting part, it is exchange part....

Answer

Alveoli is a part where exchange of gases takes place and not conduction. so the answer is C

Answer

Introduction:
The respiratory system is responsible for the exchange of gases, primarily oxygen and carbon dioxide, between the body and the environment. It consists of various components that work together to facilitate breathing and gas exchange. These components include the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli. Each component plays a specific role in the process of respiration.

Explanation:
The respiratory system can be divided into two main parts: the conducting zone and the respiratory zone.

The conducting zone:
The conducting zone includes the nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles. Its primary function is to provide a pathway for air to reach the respiratory zone.

- Bronchi: The bronchi are the main branches of the trachea that lead into the lungs. They further divide into smaller bronchioles. The bronchi are responsible for conducting air into the lungs.
- Terminal bronchioles: The terminal bronchioles are the smallest branches of the bronchial tree. They are the final branches of the conducting zone and do not participate in gas exchange.

The respiratory zone:
The respiratory zone includes the respiratory bronchioles, alveolar ducts, and alveoli. This is where the actual exchange of gases occurs.

- Alveoli: The alveoli are small, balloon-like structures present at the end of the respiratory bronchioles. They are the site of gas exchange between the air and the bloodstream. Oxygen from the inhaled air enters the bloodstream, while carbon dioxide, a waste product, is expelled from the bloodstream into the alveoli to be exhaled.

Conclusion:
In summary, the respiratory system consists of both the conducting zone and the respiratory zone. The conducting zone includes the bronchi and terminal bronchioles, which are responsible for conducting air into the lungs. The respiratory zone includes the alveoli, where the exchange of gases takes place. Therefore, the correct answer is option 'C,' as the alveoli are not part of the conducting zone of the respiratory system.
