What are the 6 structures involved in the structural framework of respiration?
Respiratory system
- Nose.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Large airways (bronchi)
- Small airways (bronchioles)
- Lungs.
What are structures of the respiratory system?
There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior.
What are the 4 respiratory zone structures?
The conducting zone consists of all of the structures that provide passageways for air to travel into and out of the lungs: the nasal cavity, pharynx, trachea, bronchi, and most bronchioles….

What are the 2 zones of the respiratory system?
The respiratory system, functionally, can be separated in two zones; conducting zones (nose to bronchioles) form a path for conduction of the inhaled gases and respiratory zone (alveolar duct to alveoli) where the gas exchange takes place.
What are the structures 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. The mucus traps smaller particles like pollen or smoke.
Which of the following structures are considered part of the respiratory division?
Such structures include the nasal cavity, pharynx, larynx, trachea, and most of the bronchial tree. The respiratory zone includes all the organs and structures that are directly involved in gas exchange, including the respiratory bronchioles, alveolar ducts, and alveoli.
What are the 2 structural division 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 7 functions of respiratory system?
The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.
What are the organs and structures of the respiratory system?
22.1 Organs and Structures of the Respiratory System. 1 The Nose and its Adjacent Structures. The major entrance and exit for the respiratory system is through the nose. When discussing the nose, it is 2 Pharynx. 3 Larynx. 4 Trachea. 5 Bronchial Tree.
What are the functions of the respiratory system?
The respiratory system is responsible for obtaining oxygen and getting rid of carbon dioxide, and aiding in speech production and in sensing odors. From a functional perspective, the respiratory system can be divided into two major areas: the conducting zone and the respiratory zone.
What structures are in the respiratory zone of the lungs?
Such structures include the nasal cavity, pharynx, larynx, trachea, and most of the bronchial tree. The respiratory zone includes all the organs and structures that are directly involved in gas exchange, including the respiratory bronchioles, alveolar ducts, and alveoli.
What is the structure of the respiratory membrane?
The endothelium of the surrounding capillaries, together with the alveolar epithelium, forms the respiratory membrane. This is a blood-air barrier through which gas exchange occurs by simple diffusion. Visit this site to learn more about what happens during an asthma attack.
