∙ 14y agoThe smallest is a segmental bronchus.
The trachea is the largest and branches into the main (left and right) bronchi which then branch several times before branching into lobar bronchi and then segmental bronchi.
Each lung is made up of lobes (generally the left lung has 2 lobes and the right has 3) and the lobes are comprised of segments.

∙ 14y agoThe 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.
Air enters the external nares, passes through the nasal cavity, travels down the pharynx, enters the larynx, moves through the trachea and bronchi, and finally reaches the alveoli in the lungs where gas exchange occurs.
Allow air to pass from trachea to lungs
The right bronchus is a passage leading from the trachea/windpipe into the right lung. When objects are aspirated, they are more likely to end up in the right bronchus than the left because its angle at the carina (the point where the trachea divides into a left and right bronchus) is more vertical/leads more straight down

The first branches off the trachea are called the bronchi. The trachea divides into two primary bronchi, which further branch out into smaller bronchioles within the lungs.
It goes: trachea Mainstem Bronchus lobar bronchus segmental bronchus bronchiole Alveolar duct Aveolus
Trachea branches to the mainstem bronchus branches to the lobar bronchi branches to the segmental bronchi to the bronchioles branches to the terminal bronchioles branches to the respiratory bronchioles branches to the the alveolar ducts finally lead to the alveoli.Or... Trachea to Bronchus (Bronchi) to the bronchioles to the alveolar ducts to the alveoli.

The trachea branches off into the primary bronchus , secondary bronchus etc all the way to the alveoli.The primary bronchus is the first extension of the trachea to enter the lungs.
The wind pipe is called a trachea. It brings air from your mouth down into your lungs. It is a straight tube at the top that separates into two branches, one going into each lung. These are the left bronchus and right bronchus.
Bronchus refers to one of the branches (air passages) of trachea that go into the lungs.
the bronchi
The trachea, or windpipe, is a tube that connects the pharynx or larynx to the lungs, allowing the passage of air.
According to a figure in my human biology book if the trachea and the Bronchus is made out of the same matter then the Trachea does enter the lung. Unless the bronchus is made out of unique tissue muscle etc.
The two branches of the trachea (windpipe) are the left bronchus and the right bronchus. The bronchi lead into each lung, and are a part of the respiratory system.
A primary bronchus is the first branch off the trachea, further branching leads to the secondary bronchus and then tertiary as you get deeper into the lung.
Structure of the tracheaThe trachea is lined by cartilage and divided into two branches. These two branches are called the bronchi. The left bronchus enters the left lung and the right bronchus enters the right lung. Each bronchus is further divided into around 25 smaller branches. These smaller divisions of bronchi are known as the bronchioles. The bronchioles carry air into the alveoli.
