Trachea
The three main parts of the lungs are the bronchi (airways that carry air in and out of the lungs), the bronchioles (smaller airways that branch off from the bronchi), and the alveoli (tiny air sacs where gas exchange takes place).
The major parts that make up the lungs are the bronchi (main airways), bronchioles (smaller airways), alveoli (air sacs where gas exchange occurs), and the pleura (membrane surrounding the lungs).
A bronchoscopy is procedure where a doctor looks into your large airways (the trachea and bronchi). These are the main tubes that carry air into the lungs.

The three main breathing organs in humans are the lungs, diaphragm, and the respiratory system. The lungs are responsible for exchanging oxygen and carbon dioxide with the bloodstream, the diaphragm helps to expand and contract the lungs, and the respiratory system includes the airways that transport air into and out of the lungs.
Choking is a medical emergency. When a person is choking, air cannot reach the lungs. If the airways cannot be cleared, death follows rapidly.
To enable the stream of air reach the lungs.
Choking Agents
respiratory
It can cause a buildup of phlegm and mucus in the airways, but not in the lungs.
larger airways in the lungs
Cigarettes, over time, hurt the lungs and constrict the airways to the lungs, therefore, air has to push through the airways, making a breathless feeling to the smoker
