The respiratory conduction zone serves several key functions: it provides a pathway for air to travel from the external environment to the lungs, helps to warm and humidify incoming air, and filters out particulates and pathogens through mucous and cilia. This zone includes structures such as the nasal cavity, pharynx, larynx, trachea, and bronchi. By performing these functions, the conduction zone ensures that the air reaching the alveoli is clean, warm, and moist, which is essential for optimal gas exchange.
conducting zones are the upper respiratory tract which is the passage of air and functions to humidify, flter and warm the air. by:- cabdulaahi niyo
The tubular airways that begin the respiratory zone are the respiratory bronchioles. These structures branch off from the terminal bronchioles and are lined with alveoli, where gas exchange between air and blood occurs. The respiratory bronchioles mark the transition from the conducting zone to the respiratory zone of the lungs.
The respiratory zone refers to the part of the respiratory system where gas exchange occurs, primarily in the alveoli of the lungs. In contrast, the conducting zone includes the structures that transport air to the respiratory zone, such as the nasal cavity, pharynx, trachea, and bronchi, but does not participate in gas exchange. Essentially, the conducting zone serves to filter, warm, and moisten the air, while the respiratory zone facilitates the actual exchange of oxygen and carbon dioxide between the air and blood.

The respiratory zone of the tracheobronchial tree includes the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli where gas exchange occurs. This is where oxygen is absorbed into the bloodstream and carbon dioxide is released from the bloodstream.

The primary functions of the respiratory epithelium are to humidify and warm the air as it enters the respiratory tract, as well as to protect the underlying tissues from pathogens and foreign particles. Additionally, the respiratory epithelium is involved in the exchange of gases, such as oxygen and carbon dioxide, between the air and the blood in the lungs.
The smallest and most distal structures that remain a part of the conducting zone in the respiratory tract are the terminal bronchioles. These bronchioles are the final branches of the conducting airways before reaching the respiratory zone where gas exchange occurs in the alveoli.
