The respiratory zone corresponds to the lung parenchyma and includes the respiratory bronchioles, alveolar ducts, and alveoli. 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.
What is part of the respiratory zone quizlet?
The conducting zone of the respiratory system includes the nose, pharynx, larynx, trachea, bronchi, and bronchioles (except the respiratory bronchioles).
What are the conducting and respiratory zone of respiratory system?
The conducting zone, which includes everything from the nose to the smallest bronchioles, moves air into and out of the lungs. The respiratory zone includes the respiratory bronchioles and alveoli and moves the respiratory gases, that is oxygen and carbon dioxide, in and out of the blood.
Which is not a respiratory zone structure?

- alveolar wall (type 1 and type 11 aveolar cells and alveolar macrophages.
- epithelial basement membrane-under the aveolar wall.
- Capillary basement membrane-fused to the epithelial basement membrane.
- Capillary epithelium.
Are alveolar sacs part of the respiratory zone?
Anatomy of the Alveoli The alveoli are located in the respiratory zone of the lungs, at the distal termination of the alveolar ducts. These air sacs are at the end points of the respiratory tract.
Is the trachea part of the upper respiratory system?
The respiratory tract is divided into two main parts: the upper respiratory tract, consisting of the nose, nasal cavity and the pharynx; and the lower respiratory tract, consisting of the larynx, trachea, bronchi and the lungs. The upper respiratory tract consists of the nose, the nasal cavity and the pharynx.
What are conducting parts?
The respiratory conducting passages are divided into the upper respiratory tract and the lower respiratory tract. The upper respiratory tract includes the nose, pharynx, and larynx. The lower respiratory tract consists of the trachea, bronchial tree, and lungs.Where does the respiratory zone begin?
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole (Figure 9), which then leads to an alveolar duct, opening into a cluster of alveoli.
Which are parts of the conducting portion of the respiratory system quizlet?What are the components of the conducting portion of the respiratory system? Nose, Nasal Cavity, Pharynx, Larynx, Trachea, Airways from bronchi to terminal bronchioles.
Article first time published onWhich of the following is part of the respiratory membrane of the lungs?
The epithelial cells of the walls of the alveoli are part of the respiratory membrane that separates the air in the alveoli from the blood in the alveolar capillaries. The endothelial cells of the capillary walls are also part of the respiratory membrane.
Where the respiratory zone of the lungs begins quizlet?
The respiratory zone begins as the terminal bronchioles feed into respiratory bronchioles that terminate in alveolar ducts within clusters of alveolar sacs, which consist of alveoli. Single layer of squamous epithelium (type I cells).
What are the 3 parts of the upper respiratory tract?
The upper respiratory system, or upper respiratory tract, consists of the nose and nasal cavity, the pharynx, and the larynx. These structures allow us to breathe and speak.
What are the 2 parts of the respiratory system?
The respiratory tract is divided into two main parts: the upper respiratory tract, consisting of the nose, nasal cavity and the pharynx; and the lower respiratory tract, consisting of the larynx, trachea, bronchi and the lungs.
What are the 10 parts of the respiratory system?
- Nose.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Large airways (bronchi)
- Small airways (bronchioles)
- Lungs.
Is there cilia in the respiratory zone?
Respiratory Zone: ↑ The portion of the respiratory tract where gas exchange occurs; found in the distal lung where alveoli are located. Cilia: ↑ Mobile, hair-like projections on the top part of cells lining the conducting zone airways; cilia move mucus along the mucociliary escalator.
What surrounds alveolar sacs?
Each alveolus is cup-shaped with very thin walls. It’s surrounded by networks of blood vessels called capillaries that also have thin walls. The oxygen you breathe in diffuses through the alveoli and the capillaries into the blood.
Where is pharynx and larynx?
The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
Is the diaphragm part of the conducting zone?
The major respiratory structures span the nasal cavity to the diaphragm. Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. The conducting zone of the respiratory system includes the organs and structures not directly involved in gas exchange.
Where is the trachea located?
Your trachea sits in your lower neck and upper chest, below your larynx. It is behind the notch at your lower throat, between the inside edges of your collarbones. In a diagram of your trachea and other respiratory organs, you can see the trachea between the top lobes of the lungs.
What are the parts and functions of the conductive zone?
The major functions of the conducting zone are to provide a route for incoming and outgoing air, remove debris and pathogens from the incoming air, and warm and humidify the incoming air. … The conducting zone includes the nose and its adjacent structures, the pharynx, the larynx, the trachea, and the bronchi.
Which of the following is part of the conducting zone?
conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Which of the following is part of the upper respiratory tract?
The major passages and structures of the upper respiratory tract include the nose or nostrils, nasal cavity, mouth, throat (pharynx), and voice box (larynx). The respiratory system is lined with a mucous membrane that secretes mucus.
Which of the following is part of the respiratory zone of the tracheobronchial tree?
The respiratory zone of the tracheobronchial tree includes b. alveoli. Other structures that are included in the respiratory zone include respiratory bronchioles and alveolar ducts. The other answers are incorrect (trachea, primary bronchi, larynx, tertiary bronchi) because no gas exchange occurs in these zones.
Is the esophagus part of the respiratory system?
The esophagus is used to transport food and liquids from the mouth to the stomach, and is not involved in the respiratory system or lungs.
What area in the brain sets the respiratory rhythm?
Respiration is controlled by the respiratory center in the brain stem in response to CO2 levels. Medulla Oblongata sets the basic rhythm of breathing (pacemaker). Pons smooths out respiratory rate and influence depth and length of respiration.
What are alveolar ducts?
n. The part of the respiratory passages beyond the respiratory bronchioles, from which the alveolar sacs and alveoli arise. The smallest of the intralobular ducts in the mammary gland, into which the secretory alveoli open.
What is the main structural difference between the conducting zone and the respiratory zone?
What is the difference between the conducting and respiratory zones? The difference between the respiratory and conducting zones is their function: the conducting zone transports the air into and out of the lungs; the respiratory zone allows gas exchange between the lungs and the blood.
What has three lobes in the respiratory system?
The right lung consists of three lobes: the superior, middle, and inferior lobes. The left lung consists of two lobes: the superior and inferior lobes.
Is the epiglottis part of the upper respiratory tract?
The Respiratory System is vital to every human being. … Included in the upper respiratory tract are the Nostrils, Nasal Cavities, Pharynx, Epiglottis, and the Larynx. The lower respiratory tract consists of the Trachea, Bronchi, Bronchioles, and the Lungs.
Is the epiglottis part of the upper airway?
It is situated directly above the trachea and makes up the lowest part of the upper respiratory tract. … While swallowing, the epiglottis closes off the airway and ensures food/liquid moves into the esophagus. GLOTTIS: The glottis is a slit in the base of the trachea, ringed by the vocal cords.
