Key Points

A network of tissues and organs called the respiratory system aids in breathing. Together with blood arteries, it also has airways and lungs.
The respiratory system also includes the muscles that power the lungs.
In Human respiratory system, there are many parts like Nose, Trachea, Larynx, Pharynx, wind pipe, Lungs, intrapulmonary bronchi, the bronchioles, and the alveolar ducts, etc.

Additional Information

The airways can be categorised into two: the upper airway systems and the lower airway systems.
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 larynx, the trachea, the stem bronchi, and all airways deeply ramifying inside the lungs make up the lower airway system.
