The trachea has the largest diameter, followed by the right main bronchus, then the left main bronchus, and finally the segmental bronchi have the smallest diameter. Lobar bronchi are larger than segmental bronchi but smaller than the main bronchi.
The trachea branches into the left and right main bronchi, which further divide into smaller bronchi within the lungs. These smaller bronchi continue to branch into bronchioles, which eventually lead to alveoli where gas exchange occurs.
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 trachea extends from the larynx to the vertebral level of the fifth thoracic vertebra (T5), where it bifurcates into the left and right main bronchi.
The trachea is the main airway in the human body. It carries air from the larynx to the bronchi in the lungs, allowing for breathing and gas exchange.
The point at which the trachea splits into the right and left mainstem bronchi is called the carina. Hope this helps.
Bronchi
Bronchi is the plural form of bronchus. A bronchus refers to the main airway that leads from the trachea into the lungs, and there are two main bronchi – one leading to each lung.
The trachea has the largest diameter, followed by the right main bronchus, then the left main bronchus, and finally the segmental bronchi have the smallest diameter. Lobar bronchi are larger than segmental bronchi but smaller than the main bronchi.
Bronchitis is the medical term used for an inflammation of the main breathing tubes called the Bronchi. The bronchi lead from the trachea to the lungs.This is bronchitis.bronchitisBronchitis

Trachea
The alveoli and bronchi are both parts of the respiratory tree. The main parts of this structure, in the order of air passing through during inspiration are: trachea, bronchi, bronchioles, and alveoli. The alveoli are distal to the bronchi, because they are farther away from the center of the body then the bronchi.
The trachea branches into the left and right main bronchi, which further divide into smaller bronchi within the lungs. These smaller bronchi continue to branch into bronchioles, which eventually lead to alveoli where gas exchange occurs.
Chronic bronchitis is a long-term inflammation of the bronchi.
