i know that the lungs is one organ.

Answer 1

Respiratory system contains nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, the lungs and the body’s exterior.

Explanation:

Pathway of the respiration:-
1.Inhalation
nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)

2.Exhalation
relaxation of external intercostal muscles & diaphragm > return of diaphragm, ribs, & sternum to resting position > restores thoracic cavity to preinspiratory volume > increases pressure in lungs > air is exhaled.

Here is the diagram of the respiratory tract:-
