Question
The nose, mouth, pharynx and larynx are called upperairway• Lower airways?
Solution
The lower airways, also known as the lower respiratory tract, include the following structures:
-
Trachea: This is the tube that connects the upper airways to the lungs. It's also known as the windpipe.
-
Bronchi: These are the two main tubes that branch off from the trachea and lead into the lungs. Each bronchus then branches into smaller tubes called bronchioles.
-
Bronchioles: These are smaller branches of the bronchi that carry air throughout the lungs. They end in tiny air sacs called alveoli.
-
Alveoli: These are tiny air sacs where the exchange of oxygen and carbon dioxide takes place. They are the final destination for the air we breathe in.
-
Lungs: These are the main organs of the respiratory system. They are responsible for the exchange of oxygen and carbon dioxide.
So, in summary, the lower airways consist of the trachea, bronchi, bronchioles, alveoli, and lungs.

The upper airway system comprises the nose and the paranasal cavities (or sinuses), the pharynx (or throat), and partly also the oral cavity, since it may be used for breathing. The lower airway system consists of the larynx, the trachea, the stem bronchi, and all the airways ramifying intensively within the lungs, such as the intrapulmonary bronchi, the bronchioles, and the alveolar ducts. For respiration, the collaboration of other organ systems is clearly essential. The diaphragm, as the main respiratory muscle, and the intercostal muscles of the chest wall play an essential role by generating, under the control of the central nervous system, the pumping action on the lung. The muscles expand and contract the internal space of the thorax, the bony framework of which is formed by the ribs and the thoracic vertebrae. The contribution of the lung and chest wall (ribs and muscles) to respiration is described below in The mechanics of breathing. The blood, as a carrier for the gases, and the circulatory system (i.e., the heart and the blood vessels) are mandatory elements of a working respiratory system (see blood; cardiovascular system).
