The respiratory zone is the site where the actual gas exchange occurs. The conducting zone is composed of nonrespiratory tissue and provides the passage for ventilation of the respiratory zone, where the O 2 and CO 2 exchange takes place. The majority of the conducting zone is lined by respiratory mucosa. Part of the purpose of the conducting zone is to trap particulate materials that could clog the respiratory zone and make it hard to breathe. The conducting zone of the respiratory tract is the area from the nose (or mouth if you bring in air thru the mouth) down to the pharynx, down the trachea, to the bronchi then finally the terminal bronchioles, which are the last part of the conducting zone. The small conducting airways < 2 mm in diameter are the major site of airway inflammation and obstruction in COPD.

The conducting portion is made up of: nasal cavities, nasopharynx, larynx, trachea, bronchii and bronchioles. Within the respiratory system, ventilatory areas can be split into conducting zones (trachea & terminal bronchioles) and respiratory zones (alveolar ducts and alveoli); the only area where gas exchange occurs is within the respiratory zone, the conducting zone is referred to as dead space (McArdle, Katch I. But all other given functions are the function of conducting zone. Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. Meaning of Conducting zone. The conducting zone is all of the passages that conduct the air through and into the lungs. Consist of smooth muscle, connective tissue and out pocketing alveoli. System. The respiratory zone corresponds to the lung parenchyma and includes the respiratory bronchioles, alveolar ducts, and alveoli. The conducting zone of the respiratory system includes the nose, pharynx, larynx, trachea, bronchi, and bronchioles (except the respiratory bronchioles). Consists of the respiratory and conducting zones Respiratory zone Site of gas exchange Consists of bronchioles, alveolar ducts, and alveoli Conducting zone Provides rigid conduits for air to reach the sites of gas exchange Includes all other respiratory structures (e.g., nose, nasal cavity, pharynx, trachea) These structures form a continuous passageway for air to move in and out of the lungs. In the conducting zone, all branches of the bronchial tree, the walls of which contain cartilage tissue and seromucous glands, are bronchi.As soon as cartilage and glands are no longer present, bronchioli are involved. Nose Provides airway Respiratory Zone. 22.1|Organs and Structures of the Respiratory System By the end of this section, you will be able to: • List the structures that make up the respiratory system • Describe how the respiratory system processes oxygen and CO2 • Compare and contrast the functions of upper respiratory tract with the lower respiratory tract Want to see the step-by-step answer? The respiratory system is furthermore divided into an upper tract (structures from the larynx upwards) and a lower tract (structures below the larynx). The conduction zone conducts air breathed in that is filtered, warmed, and moistened, into the lungs. The conducting one of the respiratory systems consists of the mouth, nose, pharynx, trachea, primary bronchi, and all successive branching of the bronchioles up to and including the terminal bronchioles. What is the primary anatomical difference that marks the dividing line between the conducting zone and the respiratory zone of the respiratory tract? Post navigation. The conducting zone comprises all parts that are responsible for air to pass so that it can reach the respiratory zone. The respiratory zone includes the respiratory bronchioles and alveoli. The major respiratory structures span the nasal cavity to the diaphragm. . In contrast to the conducting zone, the respiratory zone includes structures that are directly involved in gas exchange. The alveoli are small sac-like structures with very thin walls wrapped by capillaries (Fig. the passageways from the nasal cavity to the larynx. The respiratory system has a conducting and a respiratory zone. The conducting zone of the respiratory system brings gases into and out of the respiratory system. In the adult lung one distinguishes between conducting and respiratory zones. The lower respiratory system is a hierarchical system that can be divided into two functional and structural components: the conducting tract (airways) and the respiratory zone. Nose: nasal cavity, cartilages, nasal conchae (which bones?
